Guys had the same problem , pc is future proofed for a few years so great spec. Kept crashing and only WOWP not WOT or such from same stable. Spoke to tech support (mail obviously) and after more mails than you can shake a 30 mm cannon at !!! A report showed a missing file that for some reason disappeared in an update. It meant it had to uninstall and run a complete erase on the folder CC cleaner type of this but a bit more full on.
Reladed game and for for month or more not one crash, game set to max on everything.
Mind you you it took the right techy person to find it the first few just kept saying it’s your pc.
