Hi @Dan Bromberg ,
How did you insert picture in Excel? Paste directly, paste as link, or other ways?
Where did you store the pictures?
Where did you get the Workbook? Did this problem appear in all Workbooks or specific Workbook?
I suggest you try to open it in safe mode running the following command: Press Win + R, type " excel /safe" in the blank box, press Enter. If it works fine in safe mode, please check the add-ins in your excel and disable them.
Click File > Excel Options > Add-Ins on the left side of the dialog. Then click the drop-down arrow at the bottom of the dialog box and select "COM Add-Ins" from the list, then click the GO button. What comes up is a list of COM-Add Ins that are loaded and running.
Try to provide more information and I'm glad to help you.
