@mfro0 thanks for the report. But could you provide reproduction steps and file please?

It seems to be working fine on Windows. Here's a redone example from the forum thread referenced above:

@mfro0 is it working in the latest weekly? Please add more info, otherwise I'll close this issue.

I can confirm the crash on Ubuntu (with the same model that I shared above and that works on Windows).

I have also encountered this. If you are looking for another reproducer, load the SingleLinkage.FCstd from the attached assembly, activate the assembly, select the top faces of the two wheels ("FakeGear" meant to try to speed up animation), and apply the Gear linkage.
