It looks like the background service on macOS 13 is called 'BetterTouchTool' - but instead 'Andreas Hegenberg'
Because it doesn't give any hints to the fact it's actually BetterTouchTool I had to google who that person was and then found out it was the developer of BTT.
Unfortunately that's a limitation in macOS Ventura for such background services (and Apple has already received a lot of critical feedback about this because it's super stupid - they use the name saved in the signing certificate, which can not be changed). You probably have the process priority helper tool installed (which is not necessary anymore, so you can uninstall it here: (will probably require a macOS restart to not show up anymore)
