Describe the bug

After I ran yarn config set cache-folder by mistake, the cache-folder was set true, and almost any command of yarn crashed.

> yarn config set cache-folder
yarn config v1.22.21
warning package.json: No license field
success Set "cache-folder" to true.
Done in 0.68s.

> yarn cache dir
TypeError [ERR_INVALID_ARG_TYPE]: The "paths[1]" argument must be of type string. Received type boolean (true)

> yarn cache clean
TypeError [ERR_INVALID_ARG_TYPE]: The "paths[1]" argument must be of type string. Received type boolean (true)

> yarn
TypeError [ERR_INVALID_ARG_TYPE]: The "paths[1]" argument must be of type string. Received type boolean (true)

To reproduce

Additional context

No response

I got yarn back to normal by editing cache-folder in the .yarnrc file, but I think it could be better to return an error when such commands yarn config set cache-folder were typed.

yarn config v1.22.21

This appears to be an issue with yarn classic which is frozen https://github.com/yarnpkg/yarn

try remove .yarnrc file

I've been through something similar and removed the .yarnrc file to fix the problem.

It will happen again .yarnrc.

As noted, this is an issue with Yarn Classic. The Yarn Modern equivalent yarn config set cacheFolder true does not lead to an error.
