ACR 16.5.1 crashes when opening jpgs

I am running Ps 25.11 and ACR 16.5.1 on an M2 Studio Mac. It has been my longstanding preference to open all files in ACR when opening files in Ps. With the new ACR update (August 27. 2024), Ps crashes both 1) when I attempt to open an image file and 2) when I attempt to access preference menus for ACR. Hence, Ps and ACR are not operating at all.
