BIG PROBLEM WITH ARTBOARDS 20.0.5!!!! If i open my old PSD files with artboards (create with 20.0.4 and 20.0.0). Support told me "It normal work with old version photoshop" Adobe developers for what we pay??????????
I'm unable to reproduce this problem. Are you saying it doesn't happen with Artboards created in 20.0.5? It may help if we could see your Photoshop System Info. Launch Photoshop, and select Help > System Info... and copy/paste the text in a reply.
