The bug report page (https://community.gaijin.net/issues/p/crossout/new_issue) is broken, the Create button is permanently disabled, so I am posting here out of desperation
After launching the game through Steam or the stand-alone launcher, it crashes with no error. This usually happens after attempting to log in and sometimes before the login menu loads.
Attempted Solutions:
Repair the installation through Steam
Repair the installation through the stand-alone launcher
Uninstall, delete all remaining files manually, reinstall
Set launcher.exe, gjagent.exe, Crossout-D3D12.exe, and Crossout.exe to run as an administrator.
