all pdf pages are black
version: Adobe Acrobat Pro Continuous Release | 2023.006.20380 | 64 bit
Windows 10 Pro 22H2; OS Build: 19045.3693
About six months ago, suddenly all Adobe pages in all documents opened black. I turned to alternative but more cumbersome editing methods after that. Several times since I've searched online for solutions, but the postings and discussions on this problem are nearly non-existent. I've found suggested changes to make in Preferences, but none worked. I can open a pdf in Sumatra, Firefox, Edge, or Chrome browser without any problem. How can I correct this problem?
