Clean Project Fails on Load Makefile Project
Using CLion 2021.3.3 when I open an existing makefile project, the Load Project dialog opens prompting me to clean the project.

Clicking OK results in an error.

However, once the project is loaded, I can go to Project >> Clean, and the makefile clean runs succesfully.

Any ideas on how to fix this, so that clean works on project launch?

I think I found the problem. In CLion Preferences >> Build, Executable, Deployment >> Toolchains, I had the Make field set to use an environment variable: `${MAKE_PATH}`. This works fine when using the Build >> Clean menu option. However, I'd get the error when clean was run on project load.
The problem went away when I replaced the environment variable with the absolute make path name.
This seems to be a bug. Where can I report it?
