I have Azure Durable functions with Event Grid as a trigger point which is pointing to blob storage.
I have 8 activity functions and 1 orchestrator.
Based on the file types I receive one of the activity function is executed.
However I keep receiving the crashing message as in the image.
Based on the error message that you have shared is pointing that function failed with "System.ExecutionEngineException"
Generally , System.ExecutionEngineException exception is thrown when the CLR detects that something has gone horribly wrong.
This can happen some considerable time after the problem occurred. This is because the exception is usually a result of corruption of internal data structures - the CLR discovers that something has got into a state that makes no sense. It throws an uncatchable exception because it's not safe to proceed.
Looking at the stack trace that you have mentioned in the screen shot more over exception is pointing out DurableTask.AzureStorage.TimeoutHandler+ <ExecuteWithTimeout issue.
You can use memory dump generated by the Proactive Crash Monitoring tool to identify the function crash & associated crashing thread call stack.

Microsoft is aware of it, and it's currently as designed. It shouldn't affect your apps. https://github.com/Azure/azure-functions-durable-extension/issues/1965#issuecomment-931637193
