Not sure what caused the bug, but hopefully the backtrace helps.

update: cargo clean and building again solved the issue. Appears to be an incremental problem...

[michaelwoerister]

@simbleau, do you have a code sample for reproducing the bug?

[simbleau]

No, likely caused from renaming crates and incremental naming issues… Cargo clean and rebuild fixed the issue, there was no bad code from what I think.

[BGR360]

Possible dupe of #91696. Hopefully fixed by #91919.

[michaelwoerister]

@simbleau, this should be fixed on nightly. Can you confirm?

Confirmed.
