STM32H750IB crashing and cannot be connected to or halted with JTAG debugger

I’m running into a ‘Heisenbug’ crash (just adding or moving a bit of general code between builds makes it either crash or work), and when it crashes, the STLINK-V3MINI can’t attach, or if already attached, it fails to halt the processor.

Any tips or advice about catching it in the act or theories as to the cause?
