This issue is related to the fix mentioned in this post. Unfortunately, due to a bug introduced in that fix, we need to roll it back.
We’re planning to release another fix next Thursday (tentatively), which should fully resolve the issue.
In the meantime, you can temporarily avoid the issue by ensuring that the imported mesh has a size greater than 0.001 in all dimensions. Please let me know if this workaround doesn’t resolve it for you. Thank you for your understanding!
