Hello, I try Opera beta 42.0.2393.14, it work without crash (crashing only on settings menu).
The same with me

Opera 41.02.353.46 crashes
Bitdefender goes OK

That makes no difference, same crash

Opera 41.02.353.46 crashes when I open the browser
I just updated the browser from the previous version

I can't do anything to open the program
I get a windows popup screen that says an error occurs and the browser is closed
I cleanup the program and after a clean installing again the problem is still there

After the latest update yesterday after starting up Opera the browser crashes
I get a windows popup that the browser will be closed
