Can't recover data from Windows 10 Backup

How did make the files?
What process and application did you use to make the backup?

Thanks

Simply naming file extensions doesn’t tell us anything

I created the backup files using the built-in "system image backup" feature in windows 10. To be more precise, I followed this guide:
https://www.faqforge.com/windows/windows-10/take-full-backup-windows-10-on-an-external-hard-drive/

Did you run:

sudo qemu-img check -r all '/media/tsidia/SP PHD U3/WindowsImageBackup/DESKTOP-HG1003T/Backup 2020-03-22 140135/c3c7f9c3-0000-0000-0000-501f00000000.vhdx'

As stated in your own output?

sudo qemu-img check -r all '/media/tsidia/SP PHD U3/WindowsImageBackup/DESKTOP-HG1003T/Backup 2020-03-22 140135/c3c7f9c3-0000-0000-0000-501f00000000.vhdx' found one corruption, fixed it, then found no more errors.

After running guestmount --add c3c7f9c3-0000-0000-0000-501f00000000.vhdx --inspector --ro /home/tsidia/Desktop/Backup again I got the following error

When run with sudo it instead produces this output

guestmount: no operating system was found on this disk

If using guestfish '-i' option, remove this option and instead
use the commands 'run' followed by 'list-filesystems'.
You can then mount filesystems you want by hand using the
'mount' or 'mount-ro' command.

If using guestmount '-i', remove this option and choose the
filesystem(s) you want to see by manually adding '-m' option(s).
Use 'virt-filesystems' to see what filesystems are available.

If using other virt tools, this disk image won't work
with these tools. Use the guestfish equivalent commands
(see the virt tool manual page).

Did you add your user to the kvm group?

sudo usermod -a -G kvm $USER

Will do it (If you haven't already. You don't need to change the command). You will need to log off and on to make this active in the session (Just as in Windows)

Added. Now it no longer asks me to do it, but otherwise the output is the same.

I also tried to avoid using the -i option, so instead I run virt-filesystems which told me the only filesystem on the vhdx file is /dev/sda2. Next I run guestmount --add c3c7f9c3-0000-0000-0000-501f00000000.vhdx --ro /home/tsidia/Desktop/Backup -m /dev/sda2 and received this:

Are you reading the output or just copying and pasting. I’ve identified a few issues and resolved them just by reading your output

If you remove the:

-m /dev/sda2

Is it okay? Can you loop mount the file? I’m not overly familiar with mounting Windows backup files.

Are there guides on YouTube?

I am new to Ubuntu so I may not recognize some issues and if I do I may not know how to resolve them even if the situation is otherwise easy to get out of. I am grateful for the patience. I suppose running the command with sudo would solve the problem, but I was explicitly told not to do that when looking for the solution on the internet

Removing the -m part still results in errors. If there were working guides on youtube, I wouldn't be asking in the first place

Many people don’t think of YouTube for guides. It’s a perfectly sensible suggestion even to find out you tried it. Don’t you think?

Yes, I did try youtube for help. I found two videos on the matter. I tried both and run into errors that weren't present in the video

Does this work:
