Not Enough Ram CC20222
I know there are other posts in here about RAM but I have tried everything! This has been happening for about 2 weeks - previously PSD worked like a dream.
I have plenty of RAM, have it set to 96% in preferences. I've made sure there's room on the scratch disks, though I know that's a separate issue, I've checked just to be safe.
I can have nothing else running but PSD - including in the background - and it won't even open a picture from a smartphone. Not even a professional high resolution image, just an average image.
I have updated all my drivers. Did a diagnostic on my RAM. Checked for viruses, malware, etc. Windows 10 is up to date. I've uninstalled and reinstalled PSD 2022 three times. I've even removed my tablet.

Please help! I need to use my program it's driving me bonkers!
