Tun mode does not work with routing rules! HELP

[KappaKappaKappaKappaKappa]

I ran into a routing issue in my application and can’t figure out what’s wrong...

My configuration is set up so that the outbound in the routing profile is direct by default, meaning all traffic goes through my real IP. Then I add specific websites and processes to the proxy section that should go through the VPN.

BUT the problem is that this doesn’t work! The added exceptions (for example, YouTube or Instagram) are not being routed through the proxy. At the same time, the added processes follow the rules without any issues.

However, if I switch the default outbound to proxy (i.e., route all traffic through the tunnel), everything starts loading and working correctly.

I’ve already tried a bunch of advice from the internet, but nothing has helped. I’m even considering going back to Nekoray if I can’t find a solution here.

I’d really appreciate it if someone has encountered this issue and managed to solve it

P.S. I’ve already tried switching the TUN stack from mixed to gVisor, but that didn’t help either.

From my own experience, it won't work with localhost set as Direct DNS and without Local Override. Try choosing one of the DNS servers in the Direct DNS dropdown, other than localhost, for instance the Yandex DNS (it's ok, since it is used for direct only). Then input some DNS to the Local Override. I found out my ISP DNS and put it there.
As far as I understood, the most important thing here is to have the Local Override set, and I'm not sure whether changing Direct DNS is really important for TUN to work, but I'd suggest trying it anyway.
