I have the same problem. I have Windows 10, MC 1.19.4 and can no longer start the MC-Launcher, it starts always the update and gets stuck at about 3/4 during the update. Tried to uninstall it and do a fresh install (with new MinecraftInstaller.msi), that works, but it shows an info that there is a new version and it will be update on next start of the MC-Launcher. As soon i close it and start it again an update starts and get stuck again and repeats endless.
