Thanks for the log! I still see that some registry keys are used at the moment the user account is being closed (at shutdown), But I am not 100% sure if this is the culprit.
I can't really find any information specific to this. Could you please explain exactly step by step what you do that causes the problem?
We can still try a few things, I just don't want to make you go through extensive searching if it's not worth looking in that direction, if you know what I mean
