unexpected panic (unwrap)

[zhiburt]

Hi

Just encounter this unwrap.
I did not test it on nightly nor I checked duplicates.
So it may be either of them.

It was repeatable until running cargo clean then it got fixed.

It may be a duplicate #93317

This may be fixed in the latest nightly - can you try updating and see if this re-occurs?

[zhiburt]

Hey @Aaron1011 as I've mentioned.
After I run cargo clean I can't reproduce it.

But I guess if you think that it's addressed the issue can be closed.
