After restarting the computer, the built-in touchpad and keyboard on my MacBook became unusable. Uninstalling Karabiner restored them to normal.

My macOS version is 15.0.2, and Karabiner is version 15.2.0. After restarting the computer, I found that both the touchpad and keyboard were not working.

After multiple tests, I discovered that uninstalling Karabiner resolved the issue.
