Test for a structural break with an unknown break date / postestimation cannot continue due to collinear variables

Hi all,

I am running the sbsingle command to test for a structural break with unknown break date.

Code:

reg y L1.y x z
estat sbsingle

I get the following error code:

Code:

postestimation cannot continue due to collinear variables
r(198);

However, if I check the VIF scores on all variables implemented into the regression, there is no indication of colinearity.
What am I doing wrong? I am using STATA 15.1
Best,

Marcel
