Problem description

From time to time, for some unknown reason, target gets corrupted by the IDE and makes the compiler think it needs nightly toolchain when in fact it doesnt:

[...]
   Compiling anyhow v1.0.68
   Compiling async-object-pool v0.1.4

error: could not compile `anyhow` due to 2 previous errors
warning: build failed, waiting for other jobs to finish...

It happens in third party crates. Removing target "fixes" it.

Steps to reproduce

Just wait a bit, it will happen.

It was mentioned on the Rust Discord.

@keltia Thanks for the report. The problem is the same as #9700 and already fixed in #9901 The fix is already available in nightly build and will be published in stable next week

FWIW, this still regularly happens to me even with the newest version of the pluin.

@Kobzol it seems to be #10186 now. And we currently unsure how to fix it properly
