When tried to add brims to the model, this error popped up.

I have already seen this model today :-) The exact same 3MF was posted in #9464. This is a duplicate.

This is a different model, also this crashes while adding anything, i.e., brim and supports

This is a different model

My mistake. I downloaded the archive, but apparently accidentally unpacked the leftover file I downloaded when investigating 9464. Both filenames start with "Skeleton", which was probably too much for me to handle. I thought the contents was the same, possibly from the same source.

Ok, this is a different project. I ran it in debug mode and the backtrace is exactly the same as in #9489. We will fix it.

Ok, we fixed it and tested it. In the next release, Access Violation Error should not appear and slicing would be fine.
Closing, Thanks

\#9513 \#9489 Fix crash when brim is used - the expansion of very small drops may result in empty polygon, which the support spot generator did not reflect
Fix crashes of stability alert checker, when empty print object was passed to it
