    When I baked lighting by Progressive CPU, my static models got correctly lightmaps, but only bake reflection probe got bad result. I saw 6 errors "Image invalid format!" when bake reflection probe. I couldn't find any threads that got errors like that.
    That is my reflection probe after baked:

    Hey! This looks like a bug which we are not aware of. Could you please submit a bug report so that we could take a look? Thanks!

    Sorry I can't send my project that have error.
    So I tried export this scene to an empty project, setting quality, graphic, lighting same the original project, then bake again. But everything worked normally and there aren't any errors appear. So I can't submit a bug report :(

    In the Lighting window, open the Environment tab. Under the Environment Reflections header, set Compression to None. If that fixes the issue, it might be a compression-related issue.

    Changing compression fixes it but only on that machine as it forcefully regenerates data for the GI cache. It could still look wrong by loading the revision on a different machine. I think Unity might be loading bad cached data, or reading it incorrectly by uncompressing data that is already uncompressed. This bug was noticed on build machines using 2021.3.7f1.

    Update: the GI cache has bad data if you run a build with -nographics, in which case Unity just saves out a block of allocated memory since the GPU is not initialized to use Enlighten to generate the data, regardless if you have "Progressive CPU" selected in Unity 2021.3.7f1.
