I still have this issue despite several updates. No-one has answered my original post. Please respond or I will be ditching Adobe for good.

Same problem

I was suffering the same problem "unable to initialize backing library: lib:PlugPlugExternalObject", after switching to Mac Silicon.

Here's the fix that worked for me:

• (macOS) Users/<user name>/Library/Preferences/Adobe Photoshop <target_version> Settings
• Inside that folder, look for "tw0001.dat" and delete it or rename it to tw0001.dat.OLD (it's used for some old extension that is no longer required)

Cheers
Matt

This worked and was MUCH better than all the other "fixes/solutions" I saw regarding resetting all prefs, deleting reinstalling program, etc.  Quick and easy! I just can't believe this post hasnt been acknowledged or upvoted yet. THIS IS THE SOLUTION.  Thank you Matt!

Me, too constantly, to the point I am using photoshop Beta most the the time, because I don't get that crazy annoying pop-up
