For anyone that may face this problem, you should change java address in your launcher to something like this: C:\Program Files\Java\jdk-16\bin\javaw.exe

Browse your pc for the right address before changing.

    Another option (for those who can't change the Java location from the launcher) is to add Java to your PATH environment variable. Commented Jun 20, 2021 at 5:29

    On MultiMC in macOS, I had to install JDK 16 (as per this page) and then set my instance to use /System/Volumes/Data/Library/Java/JavaVirtualMachines/jdk-16.0.2.jdk/Contents/Home/bin/java as the Java binary under the instance's settings.

Uninstall or disable (under control panel-java) JRE, then install JDK again
