Copying between vaults gives Mac check in GCM failed error

I have two Cryptomator vaults on two different (WebDAV) servers. When i connect to both (using two Cyberduck browsers), i can't copy (click and drag) any file or folder from one vault to the other and i get "Error - Mac check in GCM failed."

Cyberduck version 8.7.1 (40770)
macOS Ventura 13.6.1
