'It appears that we don't support this file format' I keep getting this error when I open photos that I have transferred from my phone to my laptop.

I have already tried resetting my windows photo app and trying to open the photo on different apps, nothing works. I know that there is something with the photo file and tried repairing it using online websites / apps but still doesn't work. Could someone help me?

That is Windows live. What extension do your photos from the phone have?
Try these programs:

1. Irfanview https://www.irfanview.com/

2. Faststone Image viewer https://www.faststone.org/

These are my favorites. I don't even use Photo app from Windows, never have.

As Grizzly says, Irfanview is very good and free. You can also try Gimp

GIMP

GIMP - The GNU Image Manipulation Program: The Free and Open Source Image Editor

www.gimp.org

It knows a lot of file formats as does Pixillion Image Converter

NB NCH software will try to upsell you but the free version should be all you need.

GIMP knows about these file formats

Once you can get a program to open the file then you can, of course, save it in any other format that your app does understand.
Have you tried searching for the file extension with Google? That may give you some pointers as to what will open it.
