SharePoint Issues with Safari

Platform: MBP 13" 2019 - Ventura 13.3.1(a) - Safari 16.4

Ever since a recent software update (probably to 16.4), when I am on my employer's SharePoint site and click on a file (or folder) to either copy a link or move the folder, or move multiple folders, Safari either opens a window with a white background and a small, yellow spinning wheel appears for quite a while (if multiple files selected), or, if one file is selected, the browser window is greyed out and the spinning circle begins. For a while. If I wait it out, I get the "Something went wrong, Please try again or refresh the page," message. I can immediately log into the same SharePoint site with another browser, Sidekick, and I have full SharePoint functionality (would rather not run two browsers). I have cleared the Safari cache and the issue persists. Any thoughts?
