[Everything related to player, manager or match graphics is dark grey. Cannot see anything.]

Yup, that was the problem.

I was using the TCM 2020 v1.0 skin and as soon as I removed it the match appeared and my manager profile in the lockerroom appeared in the main menu. 

I guess it's a problem related to this skin's version.

Thank you so much for the time and attention, Jimmy!

Started a save with Inter Miami. I've wondered if this happened because they initially do not have a league to play at.

 

Once I open Football Manager 20 the left of the main menu is dark grey, instead of showing my manager profile and the locker room graphics.

Once I start a match in this save this happens, I cannot see anything of the match.

 

Would really appreciate if this could be solved for my save as well as I've spent a few hours building a team to have this happen...

Patiently waiting for a fix.

Thanks in advance!
