Cannot connect to a specific computer

Hello, 

This is first time im going through such a weird problem. I cannot connect to one of my laptops from any device at all.

Situtation:-

1 ) I have 5+ teamveiwer enabled devices, 2 laptops(win10), 2 mobiles (android) and 2  iPads, everyone can connect to each other but none can connect to one of the laptops. As all on safe wifi network, i dont think of any router issues.

2 ) One of the laptop (where the problem is , hereafter reffered as problematic laptop) has Ubuntu installation before and tv was working fine with it. Yesterday I installed win10 on that and now team viewer is not working on it.

3 ) TV version 12.0.72365 on both laptop and latest updated on mobiles and ipads.

What works/doesnt on problematic laptop:-

1 )  teamviewer starts normally and i can see id and pass ( it also gives standard Ready to connect (Secured Connection) )

2 ) I can connect to any device from problematic laptop.

3 ) No one else can connect to problamatic laptop.

4 ) Others can connect to problamatic laptop if that laptop is hosting a meeting (meeting mode works but remote control and file transfer doesnt when others are trying to connect)

Relevant Settings:-

1 ) Incomming LAN Connections :- active ( tried deactivating this )

What have i tried:-

1 ) reinstall teamviewer

2 ) reset windows

3) turn off windows defender and firewall ( note its a fresh windows installation was ubuntu before) no other programs installed.
