Hi Griffen,
I am Sumit, an Independent Advisor and a 3 year Windows Insider MVP here to help.
I assume when you restart, it does an undo of the update.
Let us check the Installation log to find why the update failed. Please share the following logs:
The Panther logs. Files named Setupact.log and Setuperr.log from the following path C:\$Windows.~BT\Sources\Panther
The Rollback logs: These usually are created if Windows Update rolls back. Files named Setupact.log and Setuperr.log from the following path C:\$Windows.~BT\Sources\Rollback
[Only if the error code is 0xC1900101-0x30018] The Device Install Log from C:/$Windows.~bt\Sources\Rollback\setupapi\setupapi.dev.log

As the log size might be large consider zipping everything before uploading.
