solved [SOLVED] All my OSA scripting languages have disappeared

[iandol]

Trying to run an Alfred workflow and I kept getting this error:

 

Code 1: osascript: no such component "JavaScript".

 

A google search turns up an Alfred forum post and linked think different post

suggesting to delete ~/Library/Preferences/com.apple.ScriptEditor2.plist and reboot. But in my case it didn't solve anything. Not only Javascript is missing, Applescript too:

Confirmed on the command line (osalang -l), although my Applescript and Javascript components are present in /System/Library/Components... 

➜ osalang -l

...crickets

I know this isn't an Alfred problem (though as most of my osascript is run via Alfred, this is where the problem manifests), but do any of you smart scripters have an idea of what I can do to fix this? A clean installed macOS 10.15.4 (19E287) on a mid-2015 iMac that was working pretty fine up till now. I tried reinstalled command-line tools just in case.

OK, well the voodoo that fixed this was: safe boot + reinstall the 10.15.4 combo update...
