Loss Of LAN/Internet Access With Bitdefender Total Security On Windows 11

Verb

Hi,

For a week +/- (may be after the last Windows 11 update), I can't use Bitdefender total security on 2 of my computer: I can't access LAN (NAS, Router...) or internet (any website). Not a DNS problem, same with IP (NAS or router). Firefox, Chrome, Discord, Steam ...can't access anything, except if I try to ping: I can reach everything (LAN/Internet). I also can ping a domain name, it's been resolved.

Sometimes, the problem appears a few minutes after the boot, sometimes on startup.

I tried to deactivate all Bitdefender modules (Antivirus, Firewall, Threat management...): still the same. The only way to recover access is to uninstall Bitdefender, so all work instantly.

Both of theses 2 computers use Windows 11 up-t-date on regular chan 22H2, build 22621.675). No other firewall/antivirus installed. 2 other computers, one on Windows 11 (up-to-date) and one on Windows 10, don't have this problem at this time.

At this point, I don't know what I can do...... Any idea? :/
