"Process finished with exit code 127" when trying to run a c program in CLion

Hello,

I'm on Ubuntu 18.04 and have recently installed CLion.

I wrote a simple "Hello World" program in a new project, built it successfully and tried to run it. I received a "Process finished with exit code 127" in the output window.

Looking at similar questions online, I saw that the problem is usually fixed after changing the shell path to be /bin/bash, but when I type "echo $SHELL" in terminal I see that this is already the path.

Is there any other solution to this issue?

Thanks!
