Modifying assignment details such as instructions, due dates, or attached resources.
Hi MayYeungYS,
Interesting, It looks like it takes some time, I would say quite some time in your case to switch these settings back, so I advise to come back after hours and make sure that everything back to normal.
I cannot suggest a specific time as I couldn't find one that supports it. However, Microsoft suggests waiting 24 hours if you restore a deleted Teams which is different from archiving.

I hope it will be helpful!
Regards
Nik
