@bsod I have been using Opera GX for over 1 years without any problem...

For about 3 weeks, Opera gx no longer wants to launch,
As said in the title, it crashes, then restarts, and then re-crashes and restarts, about 3/4 times before staying off.
I tried to uninstall it and reinstall it didn't work.
I also install Opera gx on my desktop in a folder named "Opera Test".
It does the same thing, (strat, crash, restart, re crash ...)

So I switched to Opera and is works

Can you help me ?

(I am French and I do not speak English very well, if you have misunderstood something please point it out to me, I will try to rephrase)
