Steps to reproduce

image

Open any number of tabs (reproduced with 1 and 2 tabs).
Open the settings tab last.
Keep the settings tab focused.
Attempt to split one of the other tabs.
Notice you're no longer running Windows Terminal.

Expected Behavior

Splitting a tab while the settings window is focused should either fail gracefully or work.

Actual Behavior

Slightly slower way to close windows terminal without being prompted.

Reproduced on WT Preview version 1.12.2931.0 also. Looks like it's trying to dereference a null pointer:

TerminalApp!DllGetActivationFactory+0x177bd:
00007ffe`3d7ba33d 488b01          mov     rax,qword ptr [rcx] ds:00000000`00000000=????????????????

Some more debug info:

PROCESS_NAME:  WindowsTerminal.exe

ERROR_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%p referenced memory at 0x%p. The memory could not be %s.

SYMBOL_NAME:  TerminalApp!DllGetActivationFactory+177bd

MODULE_NAME: TerminalApp

IMAGE_NAME:  TerminalApp.dll

FAILURE_BUCKET_ID:  NULL_POINTER_READ_c0000005_TerminalApp.dll!DllGetActivationFactory

FAILURE_ID_HASH:  {9bda705a-f16f-9bbc-bccf-35fe46a5a46c}
