Hi ErinEmery1,
Thank you for reaching Microsoft Community and I'm sorry for the issues that you are having on the Taskbar of your Surface Pro 7 after an update.
Is the device running on Windows 11 already or still in Windows 10?
Please try running these steps first on your Surface Pro 7 then see if the issue persist:
1: Run Surface Diagnostic Toolkit
See: Fix common Surface problems using the Surface Diagnostic Toolkit (microsoft.com)
2: Check for Windows Update
Go to Windows Settings > Update & Security and select Check for updates
Make sure all updates need are installed including Optional updates
3: Update drivers and firmware
Check what is the current OS Build of your Windows version by going to Settings > System > About.
Go to Download driver and firmware for Surface, choose Surface Pro
Then click the link next to Surface Pro 7 then click Download on the next page.
Choose the .msi file that matches your current OS Build and click Next.
After downloading, run and install the .msi then Restart.
4: Run System File Checker Tool
See: Using System File Checker in Windows (microsoft.com)
Kind regards,
Marrion
