I lost activation for Sudio 2021 after reinstallation of Windows 10 on this PC.
Please make activation possible.
NOTE: I have Studio 2021 activated on another PC and cannot loose activation on that PC.
However, in case the wrong PC is deactivated, you can reset the license for both PCs, and make 1/1 licenses available, and I then can reactivate both PCs.
