RDM Enterprise + PVM: hangs on google auth entry

Versions: RDM 11.0.9.0, PVM 7.0.1.0, windows 7 enterprise

1. PVM: start
2. PVM: enter google auth code
3. RDM: start
4. RDM: connect to ssh target using credentials stored in PVM
[so far, everything is OK - however, starting RDM first always result in a hang in PVM when the credentials are accessed]

5. lock windows desktop session
6. wait some time (5-15m)
7. unlock desktop desktop session
8. [forget to unlock PVM with google auth code]
9. RDM: connect to ssh target using credentials stored in PVM
10. PVM: google auth prompt appears
11. PVM: and now we're hung and will never come back

Sometimes force-quitting PVM and restarting can recover.

Basically, RDM/PVM integration seems highly unstable, resulting in PVM either locking up or no credentials ever being returned to RDM.

I don't know if my use-case is non-standard or if something could be done by me to prevent PVM from locking, other than baby-sitting it and making sure it's not auth-locked before requiring RDM.
