Last month, the FSLogix 2201 hotfix 2 (2.9.8228.50276) release was made generally available.
The fix can be downloaded from https://www.microsoft.com/en-us/download/details.aspx?id=104396.

The following changes are included in this fix:
- Resolved an issue that would cause a system crash while reading from meta tracking files in a Cloud Cache configuration.
- Resolved an issue where a logon would succeed even if when the disk failed to attach. Most commonly occurs in multi-session environments.
- Resolved an issue during profile cleanup where user registry hives would be removed regardless of the FSLogix local group exclusions.
Please note that the known issue with _local profile folders not being released after FsLogix user profile logoff is still present and not resolved.
