We have an older form that was created using the classic form designer that won't load properly for some users. Prior to this morning, the form loaded as the image on the right (below), and beginning this morning it loads as the left.

These users are using Chrome. We have cleared their browser cache, launched incognito, tried using Firefox and Edge, and rebooted their computers. All of these had the same result as the image on the left.

We haven't made any changes on this form in over a year and can't think of anything else that has changed since yesterday, except perhaps windows updates.

If you have encountered this, please let me know how you were able to resolve it. Thank you in advance!
