I have a Pipeline script that uses a Powershell step to run a PowerShell script which reverts a VM to a snapshot. This was working until 2 nights ago, about the time I updated Jenkins from somewhere around 2.87 along with a bunch of plugins. The step now hangs at

[workspace] Running PowerShell script

indefinitely, or as long as I'm prepared to wait i.e. many hours.The script and server are fine. I can run the script from various locations, including the same machine Jenkins uses, without issue and the reversion completes. I think that something that was recently changed has affected this plugin. Reverting to Jenkins 2.90 didn't help. I also tried getting the very latest pugin revisions. No change.

Thanks.
