I tried at the office on Linux on both 2.92 and 2.93 and it's fine so maybe it's a Mac thing?

Triaging note: the only other reports (T84107 and T84309) that involve `vertformat_from_shader` and crashing are from the use of the [Blender Bezier Utilities Add-on](https:*github.com/Shriinivas/blenderbezierutils), which I believe you [reported upstream](https:*github.com/Shriinivas/blenderbezierutils/issues/38) as well Bob.
The later report has a python stack trace that points to `vbo_format = shader.format_calc()` in `batch_for_shader` in https://developer.blender.org/diffusion/B/browse/master/release/scripts/modules/gpu_extras/batch.py
I am not sure if this is helpful information or not.

@riouxr could you please try the latest Blender 2.93.2 and 3.0.0 daily builds to see if this issue has already been fixed?
https://builder.blender.org/download/daily/

And please answer Pratik's question from above:
>Also: can you please mention what exactly need to be exported to recreate the crash? Only selected objects need to export or the whole scene?

Thanks!

Oh! I totally forgot about that bezier crash addon. That is still the issue. If I turn if off, it all works. It has not been fixed in 2.93 or 3.0.

As for @pratik-2 's question, anything I export, selected object or the entire, will crash Blender.

Thanks guys!
