Is it because AndroidStudio updated Java to 21?

[sake12]

OK, my bad. They changed bundled version to 21 and i was using it.

All the products on all the supported platforms already have 64-bit JetBrains Runtime 21 bundled and it will be used by default to run the IDE. If you need to change the runtime to a different version, see below. Please note that all the current IDE versions require at least Java 17 version to run. Our IDEs will not run on the older Java versions like Java 8 or 11.

Capacitor itself doesn't use kotlin and isn't configured to use any specific version, so if you use plugins that use kotlin they will use the default java version of your system.
The plugins will need to be updated to use JVM 17 instead of 21.
