When I open Opera GX (Stable 114.0.5282.123, for Windows 64-bit), the window is completely blank white and I can only close it by force quitting it (e.g. via Task Manager). When I try to uninstall it, the uninstall prompt appears for 1-2 seconds but then quickly disappears. I tried Revo Uninstaller but that also opens the Opera GX uninstall prompt which again closes too quickly to use.
I then downloaded and installed the latest version of Opera GX (Stable 115.0.5322.142), which works fine so far, but the old Opera GX is still there. How can I remove the old one?
