on windows 10, with Opera as the main web browser, I can't open any link from whatsapp web, slack, teams, etc.
Links from Outlook are opening though.
If I change the main web browser to Edge, every links from every applications are opening correctly.

I am using Opera as my professional web browser and it is synced with many others computers, some on windows, some on linux, the issue is only on windows machines.

I can provide any needed data.
