I believe this has to do with some changes on the way the GPU attributes are read or stored. The call stack ends up on file: gpu_format_format.c, function uint padding called by VertexFormat_pack.

Same issues here on Windows 10.

Edit: Never mind, fixed by the commit.

That was compiler related. VisualStudio Compiler use signed integers for enum by defaults and the bit counts were not sufficient to store all the possible values.
