If you are still running into the 0xc0000409 error code, try the fix below: use System File Checker to scan your system for errors and glitches.
Run a System File Checker Scan
System File Checker is a built-in utility on Windows 10 designed to help users scan for and locate possible corruptions in system files and restore damaged items.There is a good chance that you will resolve the error code by running a System File Checker scan on your PC. Here’s how to do it:

If, for some reason, this method didn’t work or you prefer not to perform a repair install of your system, try the next fix.
Restore the System
A system restore will take your PC to a previous state when you were not troubled by the 0xc0000409 error code.To try this fix, you need to have the system restore option enabled on your PC. Moreover, you need to have created a system restore point before all of this happens. If this is the case and you do have a system restore point to roll back to, here are the steps to take:

Now, if you haven’t created a restore point before running into the error code, we suggest you make one now — it can be of great help in fixing a wide range of system issues.
First, make sure that System Restore is enabled on your PC. On most computers, it should be on by default, but it could have been accidentally disabled.
Here are the steps to take:
- Go to Search.

- Click Create a restore point.
- Go to System Protection.

- Once you’ve entered the description, select Create.
Now that you’ve created a system restore point, you will be able to use it in any situation when you run into an “unsolvable” error. You will simply be able to take your system back in time to a point when this error was not a problem.
