Exceptions in Machine View

[UNZ]

If i run buzz in the debugger and just leave it sit there without doing anything, it throws exceptions and seems to start and stop a thread about every 1 second. Not using any fancy theme, just the regular default with pretty much all eye candy turned off:

Exception thrown at 0x75554402 in buzz.exe: Microsoft C++ exception: HRException at memory location 0x09A2F2E0.
Exception thrown at 0x75554402 in buzz.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000.
Exception thrown at 0x75554402 in buzz.exe: Microsoft C++ exception: HRException at memory location 0x09A2F138.
Exception thrown at 0x75554402 in buzz.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000.
The thread 0x66fc has exited with code 0 (0x0).

Also on exit there is another exception:
Exception thrown at 0x75554402 (KernelBase.dll) in buzz.exe: 0xE0434352 (parameters: 0x8013153B, 0x00000000, 0x00000000, 0x00000000, 0x5E6E0000).
Exception thrown at 0x75554402 (KernelBase.dll) in buzz.exe: 0xE0434352 (parameters: 0x80131505, 0x00000000, 0x00000000, 0x00000000, 0x5E6E0000).

Can anyone reproduce this too ? Only happens in machine view, the other views are fine.

I'm on Windows 10 1909 (18363.815), and i don't remember this in the past...

I tried it for about ten minutes (32bit) but nothing happened. Win10 here too.

i just tried it again and it doesn't happen always... right now it's sitting there silent, but this afternoon it constantly spew exceptions... very odd as nothing is different and i'm not even loading machines.

do you get an exception when you close it? i still get those kernelbase ones on close.

No, nothing like that.

One thing that has been happening since I got a new machine and transferred to VS2019 is I've been getting random exceptions (something to do with ucrtbase.dll) when debugging Magic but I assumed they were something to do with my project. I don't think it's happened on other projects but then again, I havn't done much other than Magic.

I'll try runnning it longer later today.

yes i get lots of exceptions with ucrtbase.dll too recently, even visual studio crashes sometimes in that (when exiting the debugger), so i think a windows update screwed something up there. my eventlog is full of VS crashes in ucrtbase.. i don't think this is our code, it's something in recent windows updates.

Oh! I assumed it was something I'd done wrong.

I'm sort of relieved but those exceptions are really annoying.
