I get a critical error doing the following:
Play a match
Die in the match
Do not leave the match in the game
Alt tab to another window while the match continues
Stay on the other window until the match ends
When the match ends the game throws a critical error and you have to terminate
Troubleshooting, I uninstalled all mods and there was no issue. I reinstalled the mods then started uninstalling one mod at a time (reinstalling each one if I still had the issue). With all other mods I usually use installed, uninstalling Score Timer fixes the issue. Reinstalling Score Timer causes the issue to come back.
I have WG Check, python, .crash files, and Event Viewer logs if any of that will help.
