Why do I not have permission to run this mpic command?

I'm very bad with the command line and have just downloaded Ubuntu (in the microsoft store) yesterday. I'm trying to compile and run a cpp file with a specific command. I'm logged in as a non-root user and this is the command I want to use to compile the file:

mpic++ circuitSatisfiability.cpp -Wall -ansi -pedantic -std=c++17 -o circuitSatisfiability

But then I get this message:

/usr/bin/ld: cannot open output file circuitSatisfiability: Permission deniedcollect2: error: ld returned 1 exit statusmpic++: No such file or directory

If I do "ls" I can see my file is in there. Via the windows file I can also see that there is a ".idea" folder. Others could compile this way, why cant I?
