LRC 15.0 crashes on startup

Hi, 

I updated ton LRC 15.0 and it keep crashing on startup, at the catalog conversion page.  

I use windows 11 25H2, windows update up to date. 

GPUs : Nvidia RTX 5060 Ti with Studio drivers up to date

Intel integrated 770 up to date

i went back to 14.5 and crashes also immediatly on startup.  The only version that work without crashing is the 14.0.  I tried to reset the preferences, but nothing changes.  Can you provide some help to fix this problem?
