My war thunder is deleting itself every time the game updates

I got war thunder on steam and for the last 2 updates when I try to update the game steam gives me an error (possibly caused for having the launcher or a game instance open, which happens in the background sometimes, when trying to update through steam) and all of a sudden 100+ gbs are freed on my ssd for no reason, the game files are still there (some of them ig) and when running integrity check everything seems fine according to steam but the game is simply deleted and I have to install it all over again

Did you have the vanilla client installed and then put the steam folder ino the same folder??

I’d clear out all installs of war thunder if you’ve even got vanilla client on there, or had it anywhere prior, ad clear it all out, and give i another go.

Also make a new folder, even clear out the game library on that drive if possible and re-create it.

Just sounds like that crazy a problem.
