Known affected Group Policy Objects are related to files and shortcuts in User Configuration -> Preferences -> Windows Settings in Group Policy Editor. Workaround: To mitigate this issue, you can do ONE of the following: - Uncheck the "Run in logged-on user's security context (user policy option)". Note: This might not mitigate the issue for items using a wildcard (*). - Within the affected Group Policy, change "Action" from "Replace" to "Update". - If a wildcard (*) is used in the location or destination, deleting the trailing "\" (backslash, without quotes) from the destination might allow the copy to be successful. Resolution: This issue was resolved in KB5018421 (https://support.microsoft.com/help/5018421). Installation of KB5018421 (https://support.microsoft.com/help/5018421) prevents and resolves this issue but if any workaround was used to mitigate this issue, it will need to be changed back to your original configuration.
