Unsupported class file major version 55

Android Studio:

Android Studio Dolphin | 2021.3.1 Patch 1

Java:

java version "1.8.0_351"
Java(TM) SE Runtime Environment (build 1.8.0_351-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.351-b10, mixed mode)

I am using the Fire TV App Builder 1.0.7.

I am still using the standard example, so I didn´t changed anything.

Gradle build is successfull, but if I run the app adb to the fire stick the error occurs.

I had to install artic fox 2020.3.1 to run it after that error. The package itself is just outdated. I'm sure someone better at development can make it work, but I'm a beginner.

Has to do with the versions of gradle, java, and all of that jazz.
