App Designer Compiled App Crashes after ~48 Hours

Hello,

I have been using App Designer in Matlab 2023b to create shareable executable so my coworkers can use it to run tests in the Lab. The application works great, until it crashes after running for about 48hours. It's very consistent, never making it much longer then the 2 day mark. At first I thought it may be a memory issue, but depending on the test, I feel like that would change the amount of time taken to crash the app? I tried forcing a memory issue and running to see if I could recreate the crash but the app just froze it never crashed. Besides running for 2 days, I can't seem to come up with any way to replicate the issue.

Each time the app crashes a .dmp file gets placed in the AppData/Local/CrashDumps folder. I used WinDbg to take a look at the .dmp files and they all seem to point to some issue with the libcef.dll file. I'm not sure what to make of it though... What would magically make the app have an issue with the libcef.dll file after running correctly for 48hours?

Any help/insights would be greatly appreciated as this has been a thorn in my side for a while now and always having to wait 48hours to see if I fixed the issue has been quite challenging.

Here is the output from the .dmp file:

Hello Nathan,

While you've considered memory leaks, the problem might be a different kind of resource leak (e.g., handles, GDI objects) in your app that manifests over time since your app crashes after -48 hours. I would advise you to monitor resource usage and see if you are able to look for trends that might point to a slow leak or a resource cap being reached.

If possible, you can also test your application in a different environment to identify if the problem is environment-specific.

You can also try to identify if specific features of your application are more closely associated with the crash.

Since the stack trace isn't very helpful, you can reach out to MathWorks Technical Support from the link below and they might be able to assist you further.

Hope this helps!
