"Invalid session token" when connecting to Windows

[gaborcsardi]

Thank you for the great action!

For some reason I cannot connect to Windows any more. I get

...
debug1: Authentication succeeded (none).
Authenticated to nyc1.tmate.io ([134.209.128.51]:22).
debug1: channel 0: new [client-session]
debug1: Entering interactive session.
debug1: Sending environment.
debug1: Sending env LANG = en_US.UTF-8
debug1: client_input_channel_req: channel 0 rtype exit-status reply 0
Invalid session token
debug1: channel 0: free: client-session, nchannels 1
Connection to nyc1.tmate.io closed by remote host.
...

Happy to share more logs if that's helpful. Connecting to Linux still works, so maybe something has changed on the Windows runner? Anybody has ideas what this could be? Thanks!

EDIT: sometimes I get a slightly different error:

debug1: pledge: filesystem
debug1: client_input_channel_req: channel 0 rtype exit-status reply 0
Internal error
debug1: channel 0: free: client-session, nchannels 1
Connection to sfo2.tmate.io closed.
