It is already tracked it #101773

As a workaround for CI export, you can try using Vulkan driver by adding --rendering-driver vulkan to the command line.

Thanks for pointing me to issue #101773 and suggesting the workaround! I tried adding --rendering-driver vulkan to the command line, and it worked perfectly in my CI setup.

You can also use --headless with --export to remove the GPU requirement during export.

Due to issues like some meshes not appearing with headless export, as a workaround, I run it on a macOS runner without using headless, but thank you!
