App from Play Store works, the source code doesn't

[XGenize]

I tried installing the app from Play Store, and both streaming and connecting to the stream work flawlessly on all resolutions except 800x480, but that's okay.

But when I try to build the source code via Android Studio and play it on my phone, it is able to connect to a stream, but it has issues in starting a stream.

When I click on start a stream, it shows the different options, ip address, qr code, and nfc as usual. But when I press connect on my other phone, I get the error: "RSTP SERVER ERROR 1 open failed: EACCES (Permission denied)".

In the ADB, I get this...

I tried changing the resolution as well, but it doesn't work. The same configuration works if I use the app from Play Store.

Help please!
