Application crashes occisonally while loading new Tilesets with Unity 6

[Mercury-Leo]

Our application crashes quite often when loading new Tilesets.
Looking at the logs, it is caused by Cesium.

This used to happen very rarely, but ever since we have updated to Unity 6, this happens a lot.

To Reproduce

I'll be honest, this is hard to reproduce cause I think this happens in very specific scenarios and it won't be easy to redo without our product.

Also important to note:
We are doing this with multiple users that are synced and access cesium-request-cache, sometimes at the same time.

1. Create at least 2 Unity clients that are in the same share server and access the same cache.
2. Move the map between new areas.
3. Zoom in
4. Zoom out
5. Move to a different location
6. Load new Tilesets
7. Crash

Setup

• Unity version: 6000.0.32f1
• Cesium: 1.14.0

Additional context

Whenever the app crashes, it shows the same stack from CreateImplementation.
There are also a bunch of SQL errors which may or may not be related.
