Just the other day I finally went to the latest version of Lightroom. 13.5.1,, I think. Anyway, I got the same prompt. I just went into the Adobe CC app and did an uninstall of Photoshop 2024, but left my preferences, then reinstalled it and it worked fine after that. No issues. I just figured it was related to the fact that I had waited so long to go from Lightroom 13.4 that there had been some photoshop updates that were specific to 13.5 of Lightroom
