All I did was add...
codeEditor: {
lib: "monaco"
}
...to the editorTheme
section of the settings file, but it didn't actually help or change anything.
@Steve-Mcl was spot on with his response except my Pi is stuck at Chromium v72 even with the latest updates from sudo apt update && sudo apt full-upgrade
.
Currently trying to figure out how to get Chromium updated on this Pi.
