While installing 15.4.1 update, LC stopped working, none of my catelogs are present. Just using LC last night before installing update with no issues

When opening it shows a box.  “Lightroom has encountered  issue updating AI edits.  Future AI edits may not be saved and could be lost.  Please contact Adobe customer support for trouble shooting.

click open recent under catelog the only catelog that comes up is LR catalog.Ircat. Under Manage Catalog, it shows LR catalog.Ircat is located under One Drive.  That is not one of my catalogs and I do not use One Drive.  It gives a choice to Remove All which I haven’t done yet.
