Hooking loaded dlls (Vs C++)

I've managed to rebuild an old project but one of the loaded .dlls fails at some point:

Looking at:

https://docs.microsoft.com/en-us/cpp/build/run-time-library-behavior?view=msvc-160

and

https://docs.microsoft.com/en-us/visualstudio/debugger/how-to-debug-from-a-dll-project?view=vs-2019

is there an easier way to see where the threads in these dlls crash without debugging them separately?

Fortunately, they're open source but it seems like a lot of headaches.

I tried setting up a breakpoint on main() but execution ends before it gets there. The dlls as well as the exe are all x64/release.
