Build LV App Crash after hours of operation (LV2025Q3 ?)

[nottilie]

Dear communitiy members.

I have a big problem since i upgraded form LV2025Q1 to LV2025Q3 but i am not 100% sure of just this upgrade caused my new poblems.

I also did some really minor changes to my code.

The build application typically runs about 5 hours without any problems or memory leaks. I tried a lot of things in the last few days to solve the problem without your help 😉

After this time the Application disappears. 

Windows event viewer always shows the same entries corresponding to this crashes.

First is a .NET null pointer or similar error shown like this.

<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">

The second is then the corresponding appcrash error.

The simple question is. Do you think this can be due to the update to LV2025Q3 or is there a "relatively easy" way to find the origin of the problem.

In my last tests is shrinked the application to a status where no .NET assemblys are used but the .NET runtime error still happens. 

This makes me really wondering.

Thank you for any suggesstions.

P.S. It is a relatively big application with a lot of external hardware access via manufacutureres driver DLLs and CLNs.

Which was working without any problems before and now just for 4-6 hours.
