Gatsby - Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './is-truthy' is not defined by "exports" in..

[judepark]

Describe the bug I tried to create a new gatsby website from a repo and tried to develop it, but now am having issues with some "is-truthy" not being defined in my exports

To Reproduce Steps to reproduce the behavior:

1. command "gatsby develop" on existing project that used to work seamlessly, but now I see this error message:
2. Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './is-truthy' is not defined by "exports"

Expected behavior I expect my old projects or even commands like "gatsby -v" to run, but now can't due to this error message.

Screenshots internal/modules/cjs/loader.js:497 throw new ERR_PACKAGE_PATH_NOT_EXPORTED(basePath, mappingKey); ^

Additional context new to coding, kinda panicking that I can't work on my old projects anymore
