Edit: I just found a way to reproduce what i did. I just alt + tab out. Right click on my desktop. Then the Computer lags for about 1 sec.
Then i pull my mouse up and click into the small PVZGW2 window... i can use everything. Strange fix for me. But it works.
I reproduced it about 3 times now with perfect timing. Idc about any fix. It works. I did it. Im happy. Thanks anyway for all of your solutions.
Edit#2: If anybody got the same problem as me. Im happy to provide a video tutorial or stuff like that. Just pm me
