System information

Godot v4.5.stable.mono - Windows 11 (build 22631) - Multi-window, 1 monitor - Vulkan (Forward+) - dedicated AMD Radeon RX 6600 (Advanced Micro Devices, Inc.; 32.0.21033.2001) - Intel(R) Core(TM) i5-10400 CPU @ 2.90GHz (12 threads) - 15.92 GiB memory

Issue description

An EXCEPTION popup appears randomly during game development. The game still runs without issue in the background. I can still control my player ship and shoot. But I cannot stop the game or select any nodes in the UI. Clicking "OK" on the popup closes the editor but the game remains playing. As soon as I click on the console window, the game immediately closes and the console outputted some more text but I didn't get a chance to read it. This issue has been happening to me whenever I spend 1 to 6 hours of development time on my game. I am not sure if it because of my C# code or because of the Godot engine itself or a combination of both. At first I thought it was because I was not disposing of public static events, but before writing this issue, I have removed all public static events from my entire project. I'm not sure what else to check.

I have created an issue about this before (which was caused in a completely separate project) and closed it because I thought the problem was solved but looks like that is no longer the case. I have experienced this bug multiple times in the past two years and I'm only reporting it now because it's become a major annoyance to me.

Another project with this issue. CSharpGodotTools/Template#160

Steps to reproduce

Happens randomly after about 1 to 6 hours of development.

Minimal reproduction project (MRP)

Only reproduced in my private project. Have yet to try and reproduce it in an MRP on latest stable version.

But if you want MRP for v4.0.beta16.mono.official [518b9e5] look at the MRP in this issue #72298

[AThousandShips]

This will be very hard to pin down without an MRP, the 4.0 issue and MRP is not relevant as it doesn't trigger the issue in 4.5 so it unfortunately isn't likely to be of any help to this

Can you please see if it happens with 4.5.1? This might have been fixed already so if you are unable to create an MRP but it won't happen if you use 4.5.1 that would be useful information

So if you are able to make an MRP that would be very useful, but otherwise this is not likely to be something we can fix unless we stumble on it or someone recognizes it and can produce an MRP to help
