@spacemanjac I am suffering the same issue, and this was the first thing I did when getting OperaGX. So I don't know what it is. I also tried several mods, and none of them worked. If someone could help us, that'd be very appreciated.
Re: Opera crashes after login to Sync I also have this exact same mistake, the only solution is uninstall and make it forget all the input, install it again and don't make the login.
I'm pretty sure this has something to do with the Windows Security but I haven't figured out how to make the login correctly, but it has something to do with that. I'm 99% sure.
