forticlient vpn Error find interface for local_gwy 0186d40a

[carloseqt443]

hello,
I am having problems with my vpn connection with forticlient.
the application makes the connection correctly, but once connected, my pc loses connection with the internet and with the server.
the version of forticlient vpn is 7.0.7.0345 and my s.o windows 11.
Checking the logs I found the following errors.
Error find interface for local_gwy 0186d40a
Did not find interface for local_gwy 0786d40a
msg="SSLVPN tunnel connection failed"
I have tried reinstalling the application, installing several different versions, even formatting the pc, but the problem persists.
As a curiosity, if I try from another pc with my user, the connection works perfectly, but on my pc, even if I try with different users, it still fails.
I appreciate any idea that can help me to solve this problem.

I thought I had but I had to do a re-image for an unrelated issue and now the problem is back, tried replicating my steps but it didn't work. Tried a different wireless device, still the same issue. I've noticed that if I run an RDP session as soon as it connects I can quite often get it to connect and then it will stay stable, despite not always being able to ping something over vpn. Very odd.
