The xev output for both left alt and right alt is given below. I could not use right alt for any purpose due to this. What could be the problem? Thanks in advance.

Open System Settings, Keyboard, Key Bindings (top right button), turn off “Key to choose the 3rd level -> Right Alt”
it was all disabled for me. So now i enabled it and choose the option “Right alt never chooses the third level” and now it works. What actually is the third, second and fifth levels? And why is it enabled even if the entire setting to choose 3rd level key is disabled?
Anyway this solved my issue but still curious on what thoose levels in keyboard are
