Camera Raw: Crash upon exiting

ACR version 11.1.0.112 (the latest I think) crashes with no error messages when I click on 'open image', 'cancel' or 'done'. The windows scatter themselves aroundand it becomes unresponsive. Bridge too. The only way to work around is to saveas a PS file, exit ACR and let it crash. Then open the file in PS.This just started recently with no other symptoms. I did just updatePS, Bridge and ACR. I have windows 7 with 16 GB ram andthese versions:

Bridge 9.0.2.219 & ACR 11.1.0.112 & PS CC 20.0.1
