After the last Photoshop-update I cannot reexport photos back to Capture one

Basic editing is done in Capture 1. For some work I send the photos to PS, do my editing and then back to Capture one. That worked fine for years. 4 Days ago the was an update for PS, since then I cannot sent the photos back to Capture one. Always the same error report

“...the photo is allready opened or wasn’t closed at some other place...”
