@MangelMaxime Looks like the Rust compiler in CI just got bumped to v1.99.
Can you please also include #5029 in the next release, as it fixes the Rust build?

[MangelMaxime]

Yes, this is probably what I have been fighting thinking it was a transient error on the CI.

I am looking into fixing the release, will be done today.
