BepInEx appears to be looking for a file that does not exist. 

 System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Program Files (x86)\Steam\steamapps\common\Valheim\unstripped_corlib'.

Sounds like either a file was deleted/renamed or there is data corruption on the disk. 

Try reinstalling BepInEx.
