After SU13 Sim freezes using vPilot 3.7.0

After MSFS SU13, when I start vPilot 3.7.0, the MSFS2020 freezes instantly !! Sound stays alive as the vpilot client does. The Sim screenpicture does not take any mouse or keyboard inputs or input from the TCA Cpts Pack devices. Win 11 runs normal on my other two monitors. Only the MSFS monitorscreen freezes. Freeze last 20 - 30 sec and after that time, Sim start working again for about 2 - 3 minutes and …it freezes again. That rhythm runs over and over again ! When a freeze occur and I close vpilot, the Sim start running immediately !! So weird…Have not had vatsim flights for weeks now and all the Simulator fun is gone. Sim runs for 2 years stable. Looking desperate for help !!!
P.S. During Sim freeze, Task Mgr shows Sim CPU use is down to zero. I installed vpilot and the hole MSFS new. I got out all add-ons. Freezes still there. Somehow, vpilot must shut down the Sim !!??

That’s a strange one, I currently run 3.7.0, SU13 on Windows 10 without issue. You said you re-installed vPilot and the Sim.

Are you trying with an empty community folder?

Yes, this issue is very strange.
Never experienced in MSFS that kind of long lasting issue.
And yes, I did run the Sim with empty Community folder.
No improvement.
My PC is 3 years old and kind of high end hardware for 4k video und high resolution photo editing.
No big Sim probs so far.
After SU13, Sim runs fine for around 2 weeks and out of the blue it starts freezing when vpilot is on.
No changes in the Sim / PC settings.
Sim runs on it’s own SSD.
