Unity crashes with bad allocation when loading tile

[charlotte-pbt]

I use Cesium in AR on a Hololens 2 headset, and after several minutes of play Unity crashes with bad allocation when loading tile. I have the impression that the problem is a memory leak in the tileset cache, because it happened as soon as I increased it.

This is the error I found in the logs :

[error] [TilesetContentManager.cpp:1120] An unexpected error occurs when loading tile: bad allocation UnityEngine.DebugLogHandler:LogFormat(LogType, Object, String, Object[]) UnityEngine.Logger:Log(LogType, Object) UnityEngine.Debug:Log(Object) Reinterop.ReinteropInitializer:UnityEngine_Debug_CallLog_FA05wu8x__otZNsgdHTnU9A(IntPtr, IntPtr*) CesiumForUnity.Cesium3DTileset:Update()]
