I don’t know of any way I can change the simulator settings back without the simulator being open.

open the UserCfg.file and change the settings back

CTD on Startup After Enabling DX12?

may be you can try to change the UserCfg.opt and following setting: PreferD3D12 0

( DX12=on is then 1 , instead 0 )
