Bug / Crash Occasional freezes when activating an Obi Solver

[josemendez]

Hi,

I'm encountering a recurring problem with Obi 5.0 and Unity 2019.3:

No matter if the "enter playmode without reload" option is activated or not, Unity will sometimes (up to 80% of the time) entirely freeze when activating the Obi Solver object. Since it's a freeze, unfortunately, I have no error log and I can't seem to isolate what exactly causes it to happen. 

All I know is that if I load my scene with the obi solver disabled, it loads, but if I load it with it enabled, it doesn't.

I will try to investigate a bit more, but I wanted to mention it here so you know about that issue.

Small precision: I have multiple scenes loaded, the examples since to work fine on their own

---

Some more update: The error seems to come from the ObiFixedUpdater class, since when I add a solver to a new object during play nothing happen, but as soon as I add an ObiFixedUpdater to the same GameObject, the editor freezes.

---

Update again:

Obi freezed in the ObiUpdater class, line 81, on        

Code:

 Oni.Complete(stepSimulation);

this never returns, but I guess I can't get my investigation any further

Hi Bill,

We are unable to reproduce this, any additional info you can give on your setup is welcome:
- Do you have more than 1 FixedUpdater in your scenes?
- Do you have multiple solvers?
