Answer 1

I had this symptom when updating from Android Studio 3.4.2 to 3.5.

In my case, the affected file was plugins/Kotlin/kotlinc/bin/kotlinc.

The cause turned out to be that while the file's contents had not been modified at all... the Unix permissions bits on it had been.

Specifically, this was a file that comes as non-executable, and I had at some point chmod'd it to executable (because it should be) in order to use it from the command line.

The fix was to set those permissions bits back, with chmod:

$ chmod a-x /PATH/TO/android-studio/plugins/Kotlin/kotlinc/bin/*

This probably isn't a super common cause for this symptom, but hopefully it will be helpful to someone else. :-) I certainly didn't remember making that change, though once I spotted it I know exactly why I made it.
