Broken extension permissions after macOS Migration

The issue described in #4375 and workaround found by @WooJoongKim0107 is still relevant with the most current release of macOS and Karabiner.
The issue: System extension permissions don't seem to transfer cleanly while using the Migration Assistant. This causes modifications to not work at all.
The workaround: Turn off "start at login", restart Mac, uninstall Karabiner, restart again, then reinstall Karabiner.
I just had this issue on macOS version 26.5.2 and Karabiner Elements version 16.1.0
