Anti-stall will not only not hinder revers being selected, but if anything it will facilitate reverse being selected as the clutch will be ‘open’ while anti-stall is on, but there is another function when anti-stall kicks-in that is not being considered. That is the anti-stall program will manipulate throttle (takes over throttle) to normally up engine revs above the point of engine stalling. When that happens, unless the driver deactivates anti-stall by manually activating the clutch paddle, the driver has no control on throttle pedal. (Leclerc to pits - ‘’I CANNOT GO ON THROTTLE’’. Which the usual FERRARI lover changed to ‘’I CANNOT GO OFF THROTTLE’’.
You are probably more experienced than me in how the Ferrari engine works, not that hard, however I'll go back to what happened to Perez in quali in canada. It's visible on his onboard on F1TV at minute 35.
Right after the crash he tries to go in reverse 2 times (his race engineer asks him "Can you go in reverse?"), and both times as soon as he engages the gear and reverses the car drops the reverse gear without the wheels attempting any movement back. Perez then asks "Why isn't it going through?", his race engineer tells him: "Press and hold reverse... Select 1st and then back to Neutral... Select 1st gear, keep the clutch held, then Neutral then press and hold reverse" and now you can see him trying to reverse and the front wheels start moving backwards, but he's stuck anyway.
Perez engine was also in anti stall mode, after all he had just crashed and his procedure wasn't to just hold and release the clutch (in fact his race engineer made a mistake on the reverse procedure by not telling him to hold the clutch first), his reverse didn't get into gear with the anti-stall and so on. The whole operation to even attempt to reverse took 1 minute for Perez who was certainly sitting there more calm than Leclerc was, it wasn't going to work in the race to take 1 minute to get the car off the barrier for Leclerc.
