cargo build failing with error ".set_exclusive(false) method not found in SerialStream"

[PureRockets]

Compiling on Windows 11 with cargo 1.67.1, could not compile radio-service with error :

error[E0599]: no method named set_exclusive found for struct SerialStream in the current scope

[PureRockets]

Removing the offending line does allow it to build (and run) but I do get the following compile warning after removing the line:
