Hello LlanPate,
Thanks for your post in Microsoft Community.
May I know if a Windows update or other application was installed before the problem occurred?
Is the current computer set to a restore point? If there is, restore points can be used to restore your PC to the state it was in before the problem occurred.
Search for "restore point" in the search bar and open it.
Select System Restore and restore from a restore point that was created before the problem occurred.
If there is no restore point and some Windows updates and software have not been installed recently. You can try to create a new account to see if the same problem exists in the new account.
The method of creating a new local account can refer to this:
If you're using Windows 10, version 1803 and later, you can add security questions as you'll see in step 4 under Create a local user account. With answers to your security questions, you can reset your Windows 10 local account password. Not sure which version you have? You can check your version.
Create a local user account
- Select Start > Settings > Accounts and then select Family & other users. (In some versions of Windows you'll see Other users.)
- Select Add someone else to this PC.
- Select I don't have this person's sign-in information, and on the next page, select Add a user without a Microsoft account.
- Enter a user name, password, or password hint—or choose security questions—and then select Next.
Open Settings and create another account
Change a local user account to an administrator account
- Select Start > Settings > Accounts.
- Under Family & other users, select the account owner name (you should see "Local Account" below the name), then select Change account type. **Note:**If you choose an account that shows an email address or doesn't say "Local account", then you're giving administrator permissions to a Microsoft account, not a local account.
- Under Account type, select Administrator, and then select OK.
- Sign in with the new administrator account.

Please feel free to let me know how it goes.
