Setting the binary (D:\SteamGames\steamapps\common\Warhammer 40,000 DARKTIDE\binaries) to comparability mode for windows 7 seems to have resolved the literal constant crashes. Been able to play 2 games so far.
Make sure to change your path. You can find it’s location by right clicking DarkTide in the taskmanager and going to “Open file location.”
You’ll still need to open the game through Steam (or however else), but when Steam launches it, it should be in compatibility mode.
