Windows 10 DISM unable to find sources with WIM file

I have a windows 10 laptop that whenever I open the start menu or edge, the windows will start flashing like another window is requesting focus, and then it will get focus back and I am unable to type as it loses and regains focus. I have tried doing an SFC, and it did not find any integrity violations. I have tried doing a dism restore by doing the following command with a windows iso mounted that I downloaded from TechNet, so I know the install.wim file is there.

dism /online /cleanup-image /restorehealth /source:WIM:G:\sources\install.wim:1

I've also tried a few different iterations, including removing the WIM from the soruces, removing the :1, adding /limitaccess at the end, but I get the same error message no matter what (The percentage seems to stop at random):

Any ideas or do I need to reset this laptop?

Update:

Windows Central has an article on how to use Dism to repair an image

This article mentions using /restorehealth with an install.wim file source. According to them, my initial suggestion was correct: the syntax needs to be adjusted (The screen shot below is from their article).

Original post:

I've used dism a fair amount--although never for this particular purpose-- and I have used the /source option frequently. It's been my experience that this error indicates that there is a typo or invalid syntax in the file path.

I've highlighted where I believe the syntax error is:

Get rid of WIM and try:

/sources:G:\Sources\install.wim
