Desktop client 1.28.0 shows empty vault

Bitwarden has just release version 1.28.0 of their desktop client. When I open it my vault is empty. Accessing the vault through the web browser shows everything is fine. Is the latest Bitwarden desktop client incompatible with Vaultwarden, or is it just me?

See windows exe client 1.28.0 cannot sync with self host server. · Issue #1924 · dani-garcia/vaultwarden · GitHub
