On Windows 11 even worse: Opera doesn't launch after upgrading to 102 version. Only spalsh screen displays and then nothing happens. The way I fixed it is to uninstall Opera with removing all user data and then install again (it's neccesacy). Of coure I lost all my unsynchronized data and installed extensions. Futhermore splash screen was displayed every time I launched Opera - not only once after upgrade. I solved it by removing this file: C:\Users\User_Name\AppData\Local\Programs\Opera\Version_Number\opera_gx_splash.exe
I think all testers in Opera company are on vacation now
