CasparCG not starting

I have a clients machine with a Caspar V2.3.1-lts stable. The server does not start and not even write to the log file. I made a redirect of the startup:

I have Visual C++ 2015-2019 Redist installed for 32 and 64 bits. Does anybody has an idea?

You know what you are doing so I’d guess there might be an antivirus or something that’s messing with it. Anything in Event viewer that gives you a clue?

Alas I just shot it down, so I cannot check event viewer. The funny thing is, that version 2.3.0 runs flawless. So for the moment the problem is solved, but it would be nice to get 2.3.1 LTS to run on it. On the other (identical) machine I have issues with the GPU. But Caspar runs ok (both versions).
