Hi @WyattLynn
Your best course of action is to contact your instructor and let them know of your issue immediately. They might have a solution or could direct you to campus tech support.
That said, in looking at the system requirements for LockDown browser, I wonder if you have Windows 11 in S mode, which is a secure mode of Windows that is often turned on by default when you purchase a computer. Some folks don't realize they have it turned on. Lockdown Browser does not support Windows in S mode. You might also try checking for any updates to Windows and your browser.
Here are the LockDown Browser Computer Requirements.

This page explains Windows S mode and has directions for turning it off.
