Every other day ACR starts like a new installation

Hello. Every other day or so when I'm opening RAW file in Photoshop, ACR starts with the welcome screen with all settings reset to defaults. I observe this behavior starting from ACR v 17 in 2 different computers (old and new) under Windows 11 24H2,  PS 2023 and 2025, NVidia studio drivers from 2 months old to the most recent. Anybody also with the same, and any suggestions to fix? Thanks.
