Error in simulink simulation official example program?

When I try to run the official example "Develop Visual SLAM Algorithm Using Unreal Engine Simulation" again, I get an error with the following statement, followed by an error with the following simulation sim "invalid or deleted object", the error is not user-friendly, it is difficult to define the error, how can I solve it? Thank you very much in advance!

Error error:executing PreShow callback "Scope404f000400000000" for block diagram "GenerateImageDataOfParkingLot": Improper arguments for waitbar.

run in R2022a

I tried resetting to the official unmodified code, restarting matlab, changing computers, etc. but still no luck!

Could you try resaving the model and running it again?

delete the "slprj" folder and some of the intermediate files "*.slxc" that were created, and then re-simulate them.
