Hello BradleyLydon, welcome to the Microsoft community, my name is Luiz Cruz, an independent consultant and I would be happy to help you.
What exactly would be the model and manufacturer of the Laptop?
As it is stuck on the login screen, I recommend that you repair the system using Windows 10 media on a USB stick or DVD.
I believe you already have a DVD or Pendrive with Windows 10, I will list other steps that may help you. Even if I have a DVD or Pendrive, I will go through the procedures to create a boot device and start it through your computer to try to recover the system.
Download the tool according to the installed Windows 10 architecture. On here:

Run the downloaded setup and click Create installation media for another computer;
Select the Language, then select the edition and architecture according to the installed Windows 10;
Connect the Pen Drive;
Click Next;
Select the USB Flash Drive option and click Next;
Click Finish;
Boot with the Pen Drive; If you don't know how to access here:

When the installation window appears, click Repair your computer;
Click Troubleshooting> Advanced Options;
Among the options presented, follow the procedures below:
Access the System in Safe Mode (Diagnostic Mode):
Click Troubleshooting> Advanced Options> Startup Settings> click Restart> press the 5 or F5 key to access Safe Mode with Networking.
Redoing the Windows 10 startup files:
Click on Troubleshooting> Advanced Options> Command Prompt> enter your Account and enter the commands:
CHKDSK /R /F X: [Enter]
Bootrec /Scanos [Enter]
Bootrec /Rebuildbcd [Enter]
Bootrec /Fixmbr [Enter]

Restore the System by deleting everything:
Troubleshooting> Restore your PC> Remove Everything.
Note: Before performing the Restore System procedure by deleting everything, we advise you to make a backup of your data. You can connect your hard drive to another computer and transfer your personal files.
I hope this helps, even more!
