As suggested by @waqarsaleem. I granted Full Disc access via System Preferences > Security > Full Disc Access for /bin /usr/bin/ruby and it worked!

Same for me... (As suggested by @waqarsaleem, thanks).
Giving Full Disc access to /usr/bin/ruby in System Preferences > Security > Full Disc Access helped.
