MIDI editor not loading in cubase 8.5

Using Windows 10 and cubase 8.5, after recording MIDI, when opening the MIDI editor application is stuck and all I can see is white screen.
Already tried reinstalling the software and checked for new updates but it didn’t help.
It worked at some point in the past on the same computer.
Any idea ?


Hi and welcome,

Please, try in Cubase Safe Start Mode. If it helps, delete your preference.
