Thanks for the report. You are running into #122508 which is fixed in the next nightly. In the mean time, you can work around this by #122508 (comment)

A workaround to this issue should be to use cargo check --release or cargo build --release which should disable incremental compilation.

Closing as a duplicate of #122508.
