I had a similar issue after reinstalling Acrobat 2022 Pro DC 64-bit on a new build with Windows 11 Pro 64 OS, where most of my Quick Tools toolbar icons were invisible (clicking on empty locations would open them).
I suspected it was a display issue, and I found that the new clean install of Acrobat had entered my Dell monitor's icm settings into the 3 options for Color Management in the Preferences menu; i.e., RGB, CMYK & Grayscale.
Resetting these to default Acrobat entries allowed all the missing hidden invisible tool icons to reappear everywhere.
I hope this relatively easy, but frustrating without any similar Acrobat Forum solutions, may help other users.
