Submit Tool crashes on invalid section

After integrating Perforce CL 50109210, we’re seeing a crash related to how the validator section is added.

In a method

void AddValidatorSectionToWidget(TSharedRef<SVerticalBox> InVBox, const FName& InDisplayName, bool InbListPreSubmitOperations);

It gets validators by InDisplayName, but the sections may not be in the array, which causes the crash. We don’t have any pre-submit operations. Could you please confirm whether this is a known issue? If yes, is there an existing fix (or planned fix)? Otherwise, should we patch this locally?

this was fixed as part of CL 50404030 replacing Validators[InDisplayName] with Validators.FindOrAdd(DisplayName)
