Launcher hijack stops working

[line-0707]

Describe the bug
It will ask you to enable the setting where the launcher hijacking does not exist, and it will not work.
(However, restarting will fix it temporarily, but the same phenomenon will occur again)

To Reproduce
Steps to reproduce the behaviour:

1. Go to 'setting'
2. Enable "to detect home button press" and "Microsoft Launcher" from accessibility.
3. Use the terminal as usual. (about 10 minutes)
4. When the Microsoft Launcher does not start, start "Launcher Hijack".
5. The message "Accessible services are disabled. Launcher Hijack features must be enabled" is displayed, so press OPEN SETTINGS.
6. Looking at the section "Services", there are no Launcher Hijack feature options (that is, referencing an error).

Expected behaviour
A clear and concise description of what you expected to happen.

Additional context
I use Google Translate because it's a little difficult for me to use English.
It may be an inaccurate word, so if you can handle it in Japanese, thank you.
