Why would table column widths suddenly become un-editable for a particular user?

[Greg Loop]

In Confluence Wiki (on prem 8.5.12), I have suddenly become unable to adjust table column widths, my mouse cursor will not change into the column width edit mode when hovering over a columns border. This happens on all Spaces, Pages, and Tables, even new pages made from scratch with new tables I create, where I can add/remove columns/rows, just not adjust the column widths.

I have cleared the cache on my Edge browser and done a Reset, the problem still exists. I've also done the same with the Chrome browser, and the same problem exists.  Both browsers are up to date.  I've checked with two of my colleagues and they are both able to edit the column widths of the same tables I try to edit. What might the problem be?

@Greg Loop Welcome to the Atlassian community

There is not a setting in Confluence that would prevent this.  Have you tried on a different computer?  Have you had your colleagues try on your computer?  It sounds like it is something to do with your computer, maybe antivirus, etc., that is preventing something from loading.
