Cannot re-open Simulink model containing Drive Cycle Source

I'm having trouble opening a .slx Simulink model containing a Drive Cycle Source Block, from the Powertrain Blockset. Once saved and closed, double-clicking the model to open it again results in a complete freeze of Simulink, infinite Windows blue circle loading symbol.

The settings are the following:

Windows 10, MATLAB R2020b Update 3

Drive Cycle Source block (any cycle), sample time 0.001 sec

Fixed-step auto Solver

Any help would be greatly appreciated

I have done some testing and the problem seems to be the Drive Cycle Source sample time. As soon as I set a sample period <1 sec, the model gets stuck in loading once I try to re-open it.

What is causing this ?

I have brought the issue to the notice of our developers. They will investigate the matter further.
