The Opera Developer version works fine

A temporary solution is to use a custom user directory.
Opera's user directory is usually in
C:\Users\<your name>\AppData\Roaming\Opera Software\Opera Stable if it isnt you can look it up under "about opera" and the appdata folder is usually hidden, just google if you dont know how to view hidden folders.

Copy everything from the opera stable folder to another folder of your choosing, lets say D:\Opera_Profile for example.
Now go into your Opera Install directory and make a shortcut to the launcher, open the Shortcut's properties
and paste the following to the "Target" field

C:\Program Files\Opera\launcher.exe --user-data-dir=D:\Opera_Profile
Adjust the Folder Paths according to your system, also it is very important to add a space after the launcher.exe, otherwise it wont work, furthermore there cant be a space in the user-data-dir for example
--user-data-dir=D:\Opera Profile instead of Opera_Profiles will not work

you will have to launch Opera with that shortcut from now on, and it doesnt work in the taskbar for some reason and pinning it to the start menu only works if you pin regular Opera on it and edit the Shortcut made by the system, it should be in C:\ProgramData\Microsoft\Windows\Start Menu\Programs

so far this works fine for me
