I'm sorry to hear that. Outlook might have image blocking enabled, which prevents the automatic loading of images in emails. To disable image blocking, go to "File" > "Options" > "Trust Center" > "Trust Center Settings" > "Automatic Download" and make sure the "Don't download pictures automatically in HTML email messages or RSS items" option is unchecked.
Instead of linking to the image hosted on Google Drive, try embedding the image directly into your email signature. To do this, you'll need to save the image from Google Drive to your computer and then insert it into your signature using the "Insert Picture" option in Outlook's signature editor. This ensures the image is included within the email rather than relying on external links.
Try to repair Microsoft Office.

If you still have issues could you please try on another PC to check if the issue persists? Thank you.
