Preliminary checks failed! Task Service Error. Method not found:

[ssaadmin]

Hello, I am getting the following error message when I attempt to deploy any package to any computer:

Preliminary checks failed! Task Service Error. Method not found: 'System.Security.Principal.WindowsImpersonationContext System.Security.Principal.WindowsIdentity.Impersonate()'. Credential: (<domain>\<domainaccount>). ShareCredential: (<LansweeperServer>\<defaultpackageshareuser>).

This began happening after I was asked to restore the database to an earlier point in time, which completed successfully. I followed the tutorial on restoring in Lansweeper's knowledgebase. I also update our Lansweeper Server to the latest version 11.1.1.3, which also completed successfully. Can anyone help shed some light on this issue for me please?

I have the same problem with the latest version of Lansweeper. It's been like this for a week now.. I think we need to wait for a patch to fix the issue
