Just to add some information to this.
I was running Citrix Workspace on my machine for some time before installing Zwift. I had been using Zwift for ~2 years without issue, until recently.
Not sure if it was caused from Zwift update, as my timeline of app updates etc is not clear, but there were no changes to Citrix Workspace.
Windows did an update for March 2023, but again, not sure if it was that or Zwift updates/changes that caused it to stop working.
