Hello,

this is a problem between the Windows component to scan the QR code and the 2fast app. Have you tried to google the HRESULT? For example: https://www.ionos.com/digitalguide/server/configuration/the-rpc-server-is-unavailable/

"DCOM Server Process Launcher" and "Remote Procedure Call (RPC)" services are running, so the fix proposed by that site doesn't apply. "Remote Procedure Call (RPC) Locator" service isn't running, but no indication it needs to be. Also, regardless of the source of the problem, 2fast should ideally handle such an error with more grace, rather than just crashing.
