Windows 11 client crash v21.1

This is the 2nd or the 3rd time happening since the 21.1 version update.
Normally playing and the game closes and shows a client crash window with 2 buttons to Send report or Exit game (btw the game is closed already) but when I press the Send report button it says no email to send to.

Cannot attach the crash report .dmp or .zip file because

Cod4x is crashing for me as well. It runs perfectly on patch 1.7. But when I install the latest Cod4x patch 21.1 it does not launch any more. It does not even start anymore. I am on Windows 11.
