Error ID: 8277831 - I cannot Deactivate All licenses on a old server before activating them into new one (and then upgrade)

Question

I have License Server Manager 18.0.79 installed on my old server (Windows Server 2012 R2) currently hosting Trados Studio 2022 licenses 
 If I click on "Deactivate all" following error pops up: 
 I also tried to make an offline deactivation without success. Can you please help me? My goal is to deactivate all licenses, then activate them on a new server (where license manager and so on in correctly installed) and configure all - same - clients for my company for such licenses before upgrading them. Thank you in advance
