Teams disconnects after 20 seconds during a call - Need urgent help for work

Hello community ,

So I've been using teams for years now with 0 issues . Last Friday , i was surprised when during a Teams call , after like 15 seconds of the call , My internet dropped , and It kept cut until i closed teams for my Laptop to connect to internet Again .

Tried Cabled Ethernet , switched to 5G access point , I even tried another Wifi connectivity .

what i can assure you is that my internet ( Fiber ) is super fine , in fact , it doesn't disconnect until i launch a team call .

Additional Information , I tried a random Google Meet call from browser ( EDGE ) and same issue happened .

What I tried until now :

-Reseting my network settings

-Reseting Teams

-Closed VPN when calling

None of the above solved my issue
