I see these lines in log_0.txt. This may indicate the issues with GPU or with the way engine addresses to it.

First, update your Nvidia driver. Then, if the problem stays, attach the callstack, if possible.

Also, please, can you answer some questions:

Does this crash occurs when you building a project in editor? 

Does it crashes on other APIs?

If you are starting a project via "run" button in SDK browser, will it crash?

Have you tried creating C++ project and build it, will it crash?

Thanks!

Good evening arizmenda,

I couldn't manage to crash the program again, but I think the cause of the crash was that the engine exceeded the maximum RAM usage. Unigine comes pretty close to the limit.

The crash happened when I started to switch from the run button from vscode to unigine's run button and vice versa. I already ran the simulation multiple times that way.  The first time the 3 error messages popped up it didn't crash the engine (Not completely sure if this first part happened because I couldn't find the crash in the log file). The second time I launched the simulation, it was laggy so I closed it, the 3 error messages popped up again, I screenshotted the screen, closed one message then 2-3 more popped up and crashed the whole engine.  I also tried to create a new project to crash the engine by repeating the steps I did in the project, but I couldn't manage to crash it. Everything works fine now.

This is the settings of the project that crashed:

Thank you for the additional info! We will check out the chance of memory leaks. If those crashes will keep appearing, try to switch the API or update GPU driver. I would also advice to clean up user cache. Simply delete contents in C:\Users\<username>\AppData\Local\unigine\Editor folder.
