Since 22.04 and 2022, the PPA for AppImageLauncher has not been built or build-attempted for over 365 days. The upstream developer says to use the "continuous build" version of the upstream GitHub repository, which publishes (though it hasn't in a while) .deb files for installation of AppImageLauncher. This .deb installs and works in Ubuntu 22.04 and Ubuntu 24.04.

Unfortunately the PPA just simply doesn't work and since the upstream developer has abandoned actual versioned releases, there's no alternative but to install from the .deb from 2022 on the GitHub repository's releases.

Note though that your mileage may vary with the usage of App Image Launcher, if there's any flaws in the code you will have to go right to the developer to get support and there is no alternative way to get updates or fixes for the package.
