Movie Render Queue works but not responding at end

Using UE 5.3.2, Most of my movie render queue works and I do find the mp4 in the folder working as expected afterwards BUT it never closes.
I tried waiting for half an hour (for a render that took 1 or 2 minutes) but windows still say UE is not responding. So I have to end its task and reopen it.
Since UE+project is quite long to load, it does waste a looot of time.
I tried fixes suggested here:

and there:

But while I now can render without crashing (I do get the result now), it now freeze UE at end. Collateral symptom: jpeg generated files are not deleted even when option is checked, I guess it hangs after movie is done (since it is there and ok) but before deleting.
Anyone having the same issue and solved it?

i also have the same things like that…any other solution?
