lsd in OS X is the LaunchServiceDaemon. launchd is a launch daemon manager!
support for launching apps and matching document types to apps. As a result, the keys recognized by Launch Services allow you to specify the desired execution environment for your bundled code.

If it continues...
Start with this of M1 or M2 Mac...
On your Mac, choose Apple menu > Shut Down.
Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.
Press and hold the power button on your Mac until “Loading startup options” appears.
Select a volume.
Press and hold the Shift key, then click Continue in Safe Mode.
The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.
Restart normally.
Open Terminal and use the following command string to do so:
sudo mdutil -E /
This basically asks for temporary super user status, which is why Terminal may ask you for your password (it may not if you’ve used a sudo command recently or are already logged in as a super user or root. The command asks the unix tool mdutil to reindex the spotlight database for everything on the computer, including external drives, mounted disk images, etc. To re-index only for a specific drive, use the /Volumes path. For example, for an external drive named “MiniMe,” the command would look like this:
sudo mdutil -i on /
Rebuilding a drive index can take a long time, so be prepared to wait whether you do it through the System Preference panel or the command line.
If still need be…
Open Terminal and run each of these one at a time
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user
sudo /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -seed -lint -r -f -v -dump -domain local -domain system -domain user -domain network
killall Dock
sudo mdutil -E /
sudo mdutil -i on /
Rebuilding a drive index can take a long time, so be prepared to wait whether you do it through the System Preference panel or the command line.
