@freeture Assuming Windows, download "Opera_GX_107.0.5045.37_Setup_x64.exe" from https://ftp.opera.com/pub/opera_gx/107.0.5045.37/win/.

Then, in Opera, goto the URL opera://about, take note of the "install" path and close Opera.

Then, uninstall Opera, but don't choose to delete your data when uninstalling.

Then, delete the install folder.

Then, delete everything in "C:\Windows\temp" and "C:\Users\yourusername\AppData\Local\temp".

Then, launch "Opera_GX_107.0.5045.37_Setup_x64.exe", click "options", uncheck "import data from default browser, adjust all the other options as you like and install.

That should fix it.
