Launcher bugged?

So, 3 years back I bought minecraft. It worked all fine and dandy until a month ago,when it crashed. My launcher is the official Minecraft launcher. I even have downloaded other launchers but they don't work either. I also need to mention that I have changed laptops(from 2016 to 2019). The output says that it crashed with an exit code 1 and could not find client net.minecraft.client.main.Main
