Hello, tagging this as General just to report the issue and our found fix. And also to let people find this solution.
So I helped my friend troubleshoot for this issue and we finally had it work by only starting it on admin mode.
His log files always listed the following but never his NVIDIA MX450 GPU even after running it on admin and making sure that it was using the NVIDIA one.
[ 0.714648] Input input_common/udp/client.cpp:StartCommunication:206: Starting communication with UDP input server on 127.0.0.1:26760

And only these 2 errors

There might be a need for Citra to report a more appropriate message in such cases.
My friend just told me that he didn’t even start it in admin mode today and it worked just fine after update nightly 1992.
