I am having this issue too. The other thread saying it was resolved by reinstalling .NET 5.0.0 did not work for me. I have tried reinstalling live, reinstalling APT-AKI, reinstalled all .NET runtimes/sdks(tried .NET 6.0.0, .NET 5.0.12), restarted pc multiple times, zero mods, correct port, zero console errors, cleared temp files, user folder. I am at a loss.
Yeah, i have exactly the same problem
