Somehow you gave me the idea to copy my laptop’s “PythonMode/” folder to my desktop PC. 💡  
And it just worked after that! 🥳

Seems like even though PDE’s Contribution Manager says it’s gonna download Python Mode build 3049, it actually downloads build 3050! 🤪

Just checked that build 3050’s “PythonMode.jar” file was compiled by Java 11. ☕  
AFAIK, Java 11 is still incompatible w/ current PDE! Needs to be at most Java 8. 😑
