We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

This seems similar to a known bug in 2024R1. 
There is a Service Pack for 2024R1 (SP3) that may help, although I would use 2024R2. 
Note: Even with the 2024R1 (SP3) / 2024R2, it will take time to open the Mechancial the first time. 
Allow Mechanical to open the analysis, then make a small change (rename a branch, add a coordinate system etc) then Save, Close and reopen.
Resuming thereafter should then be normal.Â
