IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 0000000044b64b40, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000001, bitfield :
	bit 0 : value 0 = read operation, 1 = write operation
	bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff8023f6116a4, address which referenced memory

In the stack you pasted, it looks like cbfsconnect2017 has detoured the file read attempted by cpptools.exe and caused the BSOD. I would recommend opening a bug against the LinuxReader program as this does not appear to be caused by our VS Code extension.
