MSAA as anti-aliasing method triggers Breakpoint. But TAA does not

Hi!

By having MSAA enabled as anti-aliasing method in Unreal, the editor will hit a breakpoint on startup that says “A breakpoint instrudcion (_debugbreak() statement or similar call) was executed in UnrealEditor.exe.” But when I switch to TAA as anti-aliasing method this does not happen. Does anyone know the reason behind this?

Btw, I need to use MSAA because it works best for the rendering of outlines etc.
