After I update rust version to 2021, I got compile error on WSL2 Unbuntu:

thread 'rustc' panicked at 'assertion failed: sentinel == STR_SENTINEL', /rustc/0b42deaccc2cbe17a68067aa5fdb76104369e1fd/compiler/rustc_serialize/src/opaque.rs:669:9

note: the compiler unexpectedly panicked. this is a bug.

It looks like a duplicate of #91663 , cargo clean might fix your issue as well.

Thanks for the report! cargo clean should clear it up as long as you don't switch to older toolchains. Closing as a duplicate of #91663.
