2022 SP1 runs incredibly slowly

I updated to 2022 SP1 this morning and Draftsight now runs incredibly slowly. Every action I take requires 5 seconds to process. Select a line? Wait 5 seconds. Delete a line? Wait 5 seconds. It's not tenable to work like this.

I completed deleted Draftsight (all files and registry items, per Draftsight directions) and did a complete clean install. I have also ensured that all of my computer files and drivers are up to date. No improvement.

Thank you for your help!
