How do I fix a MODULE_NOT_FOUND error for a module that I don't manually import?

I was just trying to install a shadcn package and was met with this extremely strange error:

 ERR_PNPM_RECURSIVE_EXEC_FIRST_FAIL  Command "cache" not found
node:internal/modules/cjs/loader:1275
  const err = new Error(`Cannot find module '${request}'`);
              ^

Error: Cannot find module '/Users/XXX/Library/Caches/pnpm/dlx/hx67qbkz3shxeflxwe2je2aqw4/193af67f081-15278/node_modules/.pnpm/@babel+generator@7.26.3/node_modules/@jridgewell/gen-mapping/dist/gen-mapping.umd.js'

}

Node.js v23.3.0

For reference, this was the command I tried to run that caused this error:

pnpm dlx shadcn@latest add accordion

I tried to run these commands to remedy this:

pnpm store prune
rm -rf node_modules pnpm-lock.yaml
pnpm install

I also tried to manually add the package that the error made reference to, I tried to both add it as a dev-dependency, and as a regular package, with:

pnpm add @jridgewell/gen-mapping
pnpm add -D @jridgewell/gen-mapping

Nothing I tried seemed to do the trick, so any help would be greatly appreciated!

fixed it by downgrading manually using
npm i @jridgewell/gen-mapping@0.3.4 --force
