In-game BF6 looks totally off and Gauntlet crashes - need help!

Since I got back from holidays my in-game BF6 looks totally off and foggy. Funny enough it is only the rendered gameplay/models. The menu and stuff looks fine. I reverted back to Radeon driver 25.12.1 but it didn't help. I tried any setting on/off left/right in Adrenaline and Windows. But it doesn't change. I'm lost... anyone has any tipps? I suspect something related to HDR, but also on/off hasn't made a difference. I also re-calibrated the HDR windows setting. Windows also looks totally fine. I also tried every possible BF6 in-game setting related to graphics. I gamed before with HDR on and it worked like a charm. Turning it off now (in windows) does not make a difference somehow.

On a another note: my game crashes every other time in Gauntlet and only Gauntlet! Super annoying, does anyone know a fix?
