Palworld rose quickly in popularity thanks to its straightforward, highly engaging gameplay. Yet players frequently encounter bugs and errors that can hinder enjoyment. Some report a black screen on startup, others struggle to create a dedicated server for co-op play. This guide gathers common problems and offers practical solutions.

The difficulty of getting Palworld up and running is partly due to its immense popularity. It sold a million copies in eight hours and quickly became a Twitch staple on launch day. The surge in players can overwhelm servers, prompting developers to work around the clock to fix issues.

Error not found Session 91
The Not Found Session 91 error appears when attempting to connect to servers that do not exist or when multiplayer is disabled. To resolve this, try connecting to other servers or request that the host enable cooperative mode.
Make sure the multiplayer game setting is enabled
After confirming the target server is online, verify that the Co-op option is enabled on that server.
Check your network connection settings
If the Co-op option on the server is active and the error persists, inspect your network configuration. A stable connection helps reduce interruptions during play.
If you use Wi-Fi, consider switching to a wired Ethernet connection to improve stability. If issues remain, restarting the modem or router can restore default settings.
Error Cannot host multiplayer session
Xbox players in Palworld may see the message Unable to host multiplayer session when returning to worlds they created. Overload on servers is a known cause. The developers advise temporarily disabling multiplayer mode for that world until a formal fix is released.
- From the Select World menu, highlight the affected world and choose Change World Settings in the lower left corner.
- Switch multiplayer mode to OFF before rejoining the world.
The character appears under the textures – what to do?
Occasionally, after rejoining, a character may appear beneath textures in water, making land traversal impossible. If this happens, end the session and restart. If the issue persists, toggle Co-Op mode in the game settings or relaunch the game to refresh rendering.
Error OnCreateSession Complete Delegate bWasSuccessful == false
The message OnCreateSession Complete Delegate bWasSuccessful == false indicates an attempt to join a server while its capacity is exceeded. The workaround is to run in single-player mode, disable Co-op in world settings, and continue solo until servers normalize.
Black screen when starting Palworld
Some PC players report a black screen on startup without any crashes. The issue appears to be specific to the PC version. The following steps help many players get Palworld running again.
Wait a few minutes
Developers acknowledged the startup issue and advised waiting a short period while data is gathered. After monitoring, an official update suggested waiting up to ten minutes due to startup anomalies. A notice was shared on the official Discord channel.
Disable full screen mode and run as administrator
Steam users have found that adjusting compatibility settings can remove the black screen. Here is a practical walkthrough:
- Open Steam, locate Palworld, and select Manage – Browse Local Files
- Right-click Palworld.exe and choose Properties
- Open the Compatibility tab
- Uncheck Turn on full screen optimization
- Check Run as administrator
- Launch Palworld again
Check the integrity of the game files
If prior tips fail, verify the game files in Steam. This can repair corrupted assets causing startup issues.
- In Steam, locate Palworld, choose Properties
- Go to Installed Files and select Check integrity of game files
Reinstall Palworld
Reinstalling Palworld on a different system drive can resolve stubborn startup problems. Uninstall via the Steam launcher, then install to an alternate drive.
Update your video card driver
Updating the graphics driver often clears black screen issues. Use NVIDIA GeForce Experience or AMD Software: Adrenalin Edition to check for updates. Open the respective program, go to Driver, and select Check for updates.
UE Pal Error – Crash on exception access violation
A small number of PC players encounter UE Pal Crashed – Exception Access Violation during gameplay. The crash is typically accompanied by a desktop crash. There is no official fix yet, but verifying game files or reinstalling Palworld can resolve it, applicable to both Steam and Xbox Game Pass PC versions.
Human error BP class popup
The BP Class Human Error popup appears after capturing a Syndicate goon and opening its details. The alert is harmless; simply click OK to close the dialog. The Syndicate goon model will disappear as a result.
Error No password has been entered
Players sometimes see No password has been entered when joining a shared server, even with the correct password. The issue has persisted since launch, with developers noting ongoing fixes in upcoming updates. As a workaround, set up the server as a community server so friends can join with a password until an official patch arrives.
General troubleshooting tips
Palworld can experience connection problems, especially with dedicated servers. Ensure a stable internet connection. If you are on Wi-Fi and trouble persists, switch to a wired Ethernet connection for better reliability.
Check the integrity of files after installing updates
If errors appear after updates, verify the game files again to rule out corrupted data.
- For Steam: Right-click Palworld in the library, choose Properties – Installed Files – Check the integrity of game files
- For Xbox Game Pass: Open Palworld in the library, select Manage – Files – Scan and Repair
Check whether your PC meets hosting requirements
Dedicated server requirements include:
- CPU: 4 cores (recommended)
- RAM: 8 GB or more
- Network: UDP port 8211 (default) with port forwarding
If private servers are desired, refer to the developer’s official technical guide for full server hosting specifications and port forwarding steps.
