I am having the same issue. Did you ever get this resolved? I have a AMD Ryzen 5 1600 with a AMD Vega 64 GPU. If I remove the AMD drivers Photoshop starts right up. But as soon as I reload the drivers Photoshop wont start any more. It is extremely frustrating since the card works everywhere else.
When you reinstalled, did you use he Creative Cloud Cleaner Tool? It has been known to fix a lot of stubborn problems. It is far superior to a standard install because it "deep roots" when it uninstalls. Use the Creative Cloud Cleaner Tool to solve installation problems
Thank you for the suggestion. I tried the tool this morning but still the same result. Photoshop locks up while loading. on the splash screen it says "Initializing Menus" and that is right when it locks up.
Usually when it locks up during the splash screen it means that one of the elements it is trying to load at the beginning is corrupt or incompatible. This could be elements it shares with other installed apps as well. Here are some things to try:
OTHER ADOBE APPS: If you have other Adobe apps, re-install those as well with the Cleaner Tool. Also, if you have other versions of Photoshop on your system--this can sometimes present issues.
CHECK VIDEO CARD DRIVERS: Make sure your video drivers are up to date. Corrupted video card drives is a big factor in file creation and loading applications.
WORST CASE SCENARIO: Wipe out and reinstall your entire operating system and load Adobe Photoshop first. If it works well--there is probably conflict with another software and/or corrupted file formats/codecs on your system.
So, as part of my original post I should've mentioned that I have been working on this issue for a few months now. I am using a AMD Vega 64 from Sapphire and the drivers are the most up to date. Also I re-formatted and re-installed Win 10 on Friday and when I posted my issue here, I was working off a fresh install with only Lightroom CC and Photoshop along with the for recent Adrenalin Drivers from AMD. The only difference was that I have never tried the Cleaner Tool. I will give that a shot uninstalling everything and see if that works. Although I am not sure how different that is then the clean install.
Thank you, I really appreciate you trying to give me advise. As I said I have been dealing with this issue since February and have not been able to get it resolved. Only Photoshop and Davinci Resolve give me any issues. Resolve stars up but crashes the same way Photoshop does when I try to add media to the pool. It is driving me crazy.
