Pcloud open existing safe in Windows

I have worked with a Cryptomator tresor in Pcloud since several years. Now I have bought a new PC and want to use my tresor on the Pcloud drive P:. I can choose the masterkey file in the Cryptomator app, but to use the safe, but then Cryptomator gets an error loading the safe.
How can I use an existing safe on a new PC?

Hi.
Please send the error message.

The error messags is “Fehler beim Laden des Tresors” (Error on loading of the safe).
This is the Error log:

Does inside your vault storage location a file named vault.cryptomator exist? It should be right next to masterkey.cryptomator. If not, you have a legacy vault and suffer from the same problem as described in Can't open vault after upgrade to 1.16.2 - #2 by infeo.
