A320NX FBW Experimental Latest (09/19/2021 - 7de8f12) - Not allowing changing sim rate?

I should also add that, before the latest versions, I used to have a CTD 1/3 to 1/2 of the flights, just after take off.
Now, with these latest versions I have had no CTD so far!
(The CTD were not sim-rate related, as I always take off at 1x, but you may have changed something else which somehow made your aircraft more stable)
