I’ve tried everything I can find online about this problem so I thought I’d try here. I get this error everytime I start the bot up on my Raspberry Pi 3B+

Same issue reported at:

https://community.phantom.bot/t/a-fatal-error-has-been-detected-by-the-java-runtime-environment/6781

I didn’t find that one but I reinstalled the OS and it somehow worked out with a little finesse

I had issues on Raspbian with Open JDK too.
Purge open JDK and install oracle-java8-jdk package.
