This worked for me but I'm still finding the trackpad to be intermittent and the Micro USB is still disconnecting and reconnecting which is a major issue as I'm using a 512gb as my OneDrive storage.

I would recommend recovering your device from a recovery
I'm sending you the steps to download and install Surface recovery image for your device.
1- Open this link to download the windows file: https://support.microsoft.com/en-us/surfacerecoveryimage
2-Scroll down the page and select ‘"Continue without signing in”, please select the Surface model, enter the serial number, select “continue”.
Please download : Surface Pro 7 - i5/8/128 M1866 - Windows 10 Home Version 1903
3-Select “Save as” and save this file to your PC desktop (that would be easier to find).
This is a pretty bigfile, it might take a while depending on your internet speed. (It's completely normal).
DO NOT save this file into the USB drive.
4-Let’s format the USB. Insert the USB drive, open the windows file explorer >> select “This pc” >> Select the USB drive, right click on it >> Select “File system as FAT32” from the drop down menu, you can do a quick format and the USB will be
ready.
Remember to use a USB thumb drive with 16gb or 32gb ( no bigger than that).
Once the windows file is downloaded, you will need to extract the file and send it to the USB drive already formatted. Please do not create any sub folder inside of the USB drive.
Locate the file recently downloaded, right click on it, select 'extract all", browse the computer and select the USB drive.
Once, the extraction is completed, move on and start with the installation process.
1- Turn off your surface device > Insert the USB drive > Press and hold the volume down button and power button at the same time for 15-20 seconds.
You should see a blue screen prompting to choose the language and keyboard layout.
2-Select "Troubleshoot" > Recovery from a drive > Skip bit locker recovery key (If prompted) > Select Fully clean the drive > Recover.
Make sure to plug in the power supply, the installation process takes 45 minutes up to an hour.
