All Amplify CLI commands fail with EBUSY error after upgrade

### How did you install the Amplify CLI?

_No response_

### If applicable, what version of Node.js are you using?

14.15.3

### Amplify CLI Version

### What operating system are you using?

Windows

No changes.

### Describe the bug

After running `amplify upgrade` and successfully installing version 12.0.0, all attempts to run any amplify command generate the following error:

🛑 EBUSY: resource busy or locked, rmdir 'C:\Users\9037568\.amplify\lib\amplify-dynamodb-simulator\emulator'

When I tried deleting that folder manually I got an error from the OS saying it was in use by another process, so I suspect the upgrade left something running, but I've been unable to identify what that is.

### Expected behavior

Upgrade should not kill the CLI.

### Reproduction steps

Upgrade.
Run any amplify command.

### Project Identifier

Can't because all amplify commands fail.
