BeardLib may fail to update if you update from old versions. If you crash after updating, try reinstalling BeardLib manually. The issue should be fixed as of 5.0.6.
It happened due to files that start with a dot such as .gitignore, past BeardLib versions (such as 5.0.3) shipped with them by accident. 5.0.4 and above do not come with them. If you see such files or folders make sure to delete them from the BeardLib folder. If you are on 5.0.6+ this issue shouldn't occur.

The mod that seems to be crashing is "Convert Gangsters" and possibly not LAS.
After removing the mod it worked for me and my friend.
try removing the mod or fixing it yourself.
