CS7038: Failed to emit module if new collection syntax is used with an implicit ImmutableArray operator.

[korsarNek]

Version Used:
.Net 8.0.302, also occurs with 8.0.301, I haven't tested other versions.

Steps to Reproduce:

sharplab

The error occurs locally with .Net 8.0.302 of the sdk and on sharplab with main (11 Jun 2024), if I choose "Default", the error becomes CS1061 instead of CS7038

Diagnostic Id: CS7038: Failed to emit module

Expected Behavior: CS1061

Actual Behavior: Outputs the cryptic error CS7038: Failed to emit module

The code is based on the omnisharp container, that's where I encountered the error. I reduced it to the minimal version where I was still able to get the error, the implicit operator from ImmutableArray seems to be important for this. The original container class has a bunch of other operators, but they don't seem related to the error.
