NX Clietn silent crash (6.0.5.41290)

Hi,

I am encountering recurrent crash from NX client  version 6.0.5.41290 on a fresh install on Windows 11.

The client crash (window dissapears from screen) without any warning, after random delay and random click. Sometimes it works for about 5 minutes, sometimes logner when mouse is never used. 9 cameras stream from local server are displayed in low resolution.

The log are set to DEBUG. The output is the following. I can't foind the real reason of the application crash. Can you help me to find it ?
