This is the forum for WatchFacestudio. The question must be asked in the forum for Galaxy Watch Studio. But you have to delete the TW4.tpk in the Galaxy Watch Studio / Workspace folder. Then try sending the file to the watch. The error message should be resolved

Thank SG,

I moved the topic to GWS for Tizen. This seems to be coming up more often now that Windows 11 is rolling out. Designers have to create a new Distributor Certificate (and RSA Acceptance) with the updated System for Windows 11.
