Interesting! That seems to be a shader issue - it looks like you're running on Windows, make sure the "HaigureSim.exe" file is being run from the "HaigureSim_August2021" folder. It needs to have the following files/folders in the same directory to function properly:
HaigureSim_Data
MonoBleedingEdge
HaigureSim.exe
UnityCrashHandler32.exe
UnityPlayer.dll
