Nobody can tell you anything without proper system info or other technical details like exact version of Ae.
Version of AE is actual (CC 17). The problem existed also in an earlier version.
My PK specs:
intel core i5-4460
nvidia gtx 960
16 GB memory
I think the problem is not in my PK spec.
In Photoshop or other Adobe program everything's ok when I change my keyboard language, but in After Effects .... the program just doesn't respond and hangs.
Is there anyone who can help???
I had a similar problem, but after running ctfmon.exe the problem was solved. ctfmon.exe can be added to startup if it was previously disabled.
