Bug Batch-mode Build Error: Type has an extra field and thus can't be serialized

    We're getting the following error while trying to do a batch mode (command-line) build with Unity LTS 2022.3.4f1, wonder if there is any way to get around it?

    Type 'X' has an extra field 'y' of type 'System.String' in the player and thus can't be serialized 

    From some searching it seems others have encountered similar errors intermittently and that it is a known unity bug. For us its happening consistently in one of our machines when triggering the build from command-line with batch mode. Building from the Editor on the other hand with the same configuration everything builds ok.

    Thank you,
