Acrobat Preflight in Production tools is working slow and crashing the software

Almost every day, my team and I use the production tool to check make sure files are on spec before we release to vendors and pubs. Since last week 9-21-2021, I have noticed that the preflight interface is working slower and crashing the program. I have tried restarting my system, checking for updates, uninstalling Acrobat and reinstalling. Nothing seems to help. There must be a bug in the system. Anyone else having this issue?
