Alternatively, you can wait about 5 minutes and then try to reconnect to another server; ProtonVPN servers periodically delete old and inactive sessions.

If you had a connection that didn’t close properly (WiFi failed or your device crashed unexpectedly), the ProtonVPN client will detect such connections and close them after a while.
