Thunderbird 128.1.0esr only work in troubleshoot mode

I migrated to a new computer with Windows 11 and to the latest TB nebula. I copied the profile folders to the new system and it imported 20 years of email correctly. BUT every connections seems to hang and eventually times out. It almost looks like TB blocked by a firewall. Even checking for updates eventually times out. HOWEVER everything works fine in troubleshooting mode.

I have no add-ons installed. I have no VPNs or additional firewalls. Disabling Windows firewall entirely doesn't change anything. I tried "Make the changes and restart" with no success. I added thunderbird.exe to the exceptions to the windows firewall and even added a rule. I tried uninstalling and reinstalling.

Is there any setting related to the connection that would be different in troubleshoot mode? Apparently nobody has ever experienced this problem, I feel like I'm going insane.
