Greetings Audioseabass!
Thank you for reporting your situation regarding your game crashing.
Our team is currently aware of this issue and the workaround is to delete the following file:
Conan Exiles\ConanSandbox\Mods\modlist.txt and manually unsubscribe from all your Conan modes. This will guarantee that mods are not loaded, if you’re using them.
Also, make sure to verify the files of the game and restart you computer after doing so.
Additionally, we suggest for you to use the Steam option to ‘‘change accounts’’ in order for the system to force Steam to disconnect your account, and then please try to play online again.
Ultimately, if nothing has worked so far, we encourage you to unistall the game, by making sure to delete all the game folders and reinstall the game.
Please let us know if the issue persists after performing the suggested steps Audioseabass.
Thank you for reaching out to us!
