I have been getting a crash lately, looking at it with dmp file. It seems to be Unity’s Navmesh that caused this. Project was very near being finished, yet this bug keeps popping up randomly. It may be related to Offmesh links that were auto-generated. Anyone else with the same issue?

Same here, please help
Yes, this is crashing unity very often for me, any solution? Im on unity 2021.1.12f1, its not fixed.
edit: trying 2021.2.0b1 will see how it goes.
@radiantboy Are you sure it’s still this crash? We’ve encountered a lot of these, but after upgrading to 2021.1.9f1 reports stopped coming. We’re now at 2021.1.12f1, no more errors encountered.
I can confirm that at least for us, this is fixed.

still crashing here on 2021.1.12f1, might be a slightly different bug 
When it crashes, get “dmp” file, drop it into Visual Studio, click “Debug with Native Only” and check what’s on call stack.

Seems like exactly the same thing as before. Maybe report the issue and include the dmp file so they can easily fix it…
Thanks. I wonder why its ok for you guys? Do you use navMeshObstacles, or NavMeshLinks?
Argggh…

Yes, we use both links and obstacles. Do you update NavMeshes during gameplay (when agents are looking for paths)?
Are you “moving” NavMeshes continously? That would result in RemoveNavMesh, AddNavMeshData being called every frame. There were some issues with that, maybe they only fixed “half” of the problem…not sure.
We’re adding and removing NavMesh parts, but with quite low frequency (once every 10s or so in average).
