Can't Attach Boot Volume after Detach (always auto-detach after attach)

Summary

No longer able to attach back boot volume after detach

Content

As per the title, I detached the primary boot volume of my compute instance, and now is unable to reattach back the same boot volume,

The attach process does not return any error. When attaching, it seems to take longer than usual, and at some point, will change to Detaching and eventually become Detached again. This causes my instance not working at all and unable to do anything.

Can anyone give any clue on this issue? Thanks in advance.
