Acronis Development team is working on a fix.

In the meantime, you can follow the workaround below.


  1. Uninstall the Cyber Protect agent fully from the machine (don't keep the logs)
  2. Make sure the following file doesn't exist in the machine: C:\ProgramData\Acronis\Agent\var\sync-and-share-agent
  3. Install the C22.06 version of the agent from here
