I do use MakeMKV not very often and I do remember that I did have the same exact problem for years and somehow always found a way for it to work. But not this time

I have already restarted my laptop after the installation both with the usb dvd drive on and off.
I have started MakeMKV with both the drive on and off and dvd inserted or missing - nothing worked.
In the past, I had to do it in a certain order but for the life of me, nothing works. And I do need to save this dvd

I can access the drive via the explorer.
Does anyone have any ideas?
