Power BI Desktop November 2019. Slow when adding and modifying a new column

I have a PBI file (size 280 MB)

When using PBI Desktop October 2019 update it took about 90 seconds to add a new column and modify the currency and decimals.

When using PBI Desktop November 2019 update it takes 5 minutes to add a new column and modify the currency and decimals.

Users on my team have also noted significant slowdown over the past 2 days when using our PowerBI dashboard, which usually ranges between 100-250MB depending on the amount of data ingested during each run.  General slowness all around:  delays when switching between tabs, interacting w/ visuals is laggy, ribbon tabs & buttons are not responsive, query editor interface becomes unusable, etc.  Things were fine 3 days ago, so presumably this is from the November 2019 update and not our data model, which is unchanged since Oct 30.
