Use Rufus on a different computer. Click the dropdown besides Select and choose Download. Then, click the Download button. Choose Windows 10 21H2. Select a pen drive to apply the Windows bootable to. Leave it in GPT mode for UEFI (non-CSM). Once it finishes, safely remove the pen drive and insert into the problematic laptop. Boot from the pen drive and click Next, then click Repair Your Computer. Troubleshoot > Reset This PC. Media created with Rufus is much more reliable and free of problems than that from Microsoft's own tools, so it should work this time. Your laptop isn't screwed, only the existing Windows is.
