Hi,
I cannot reproduce this issue on my pc. I checked attached logs and it seems that crash is caused by some mission in your MPmissions directory. Could you please try move your missions to another folder and try without user missions. If this helps try return missions by one by one to figure out which mission causes this issue. Could you please attach mission which causes this crash if you find which one it is? Thank you.

Blank profile still crashes, no mpmissions

This is the error that occurs on crash "Include file a3\3den\UI\dikcodes.inc not found."

Hi,
could you please try verify game data? https://support.steampowered.com/kb_article.php?ref=2037-QEUH-3335
Do you have same issue in main branch?
