Solidworks 2019 SP03

New computer

Solidworks has been running fine on the new computer all last week. It initially opened fine and worked perfectly this morning. However, I needed to close out of SW, make some changes to a part number on our PDM (I had just had the part open, so I closed down to make sure it was not stored in cache). All I did was change the part number on the folder, the part and the drawing (using file explorer).

Start Solidworks back up, hit the "OPEN" folder and ....crash

So, I try going through File>Open...crash

The error reporting also crashes out on both of these.

However, I can open file explorer and click on a part and it will open fine.

I have already attempted a repair through control panel.programs....still no luck.

Anyone experience this and know what might be wrong?
