Windows 10: Paint cannot open files with spaces in filename anymore

So just last night I noticed that my Microsoft Paint application stopped working. I could not reinstall it through the settings apps nor could I find it on the Microsoft store, so I had to make a risky move and reinstall it via a 3rd party website. Not only did this update the icon for it, but also it's now causing a huge issue for me.For some inexplicable reason, it will not open images with spaces in the filename. I will get an error saying "c:\users\[my name]\desktop\[first word in the file name].png was not found". This also applies to folders that have spaces in the filename too, because

Paint 3D cannot open STL files

Please update Paint 3D to be able to open STL files. View 3D *can* open them just fine.

When I open them in View 3D, and click the "Paint 3D" button, it gives this error message:

"We couldn't open Paint 3D. Wait a bit, then try again."

I did, and it keeps failing. So then, I manually go to Paint 3D, and open the file from there. In order to do that, I have to enter "*.*" as the filename, otherwise it won't pop up. The file types dropdown doesn't list STL files. But that's for good reason,
apparently, because Paint 3D says:

"Paint 3D can't read this file. It may be invalid, or in a format that we don't currently support."

So, recap:

1) The file is completely valid, because View 3D can open it just fine

2) Why can Paint 3D not open a file, while View 3D can?

3) Please add this functionality to paint 3D. It's an industry standard file type for 3D models.

This is on Windows 10.0.15063.

Photos are opening with Paint instead of Photos app

Hello,

Paint to the Photo app, we suggest that you perform the following steps:

• On the Start menu, select Settings.
  
• Go to System, then go to Default apps.
  
• Select Photos or any app that you like to be the default under
  Photo viewer.
