Describe the bug

Switching from node-modules linker to pnpm or pnp causes this error:

➤ YN0000: ┌ Link step ➤ YN0001: │ Error: Failed to open the cache entry for @next/swc-darwin-x64@npm:14.1.4: Couldn't allocate enough memory at Zi.allocateBuffer (/Users/paulnispel/src/bb/basicblock/.yarn/releases/yarn-4.7.0.cjs:149:204603)

have tried on many version of yarn and many version of node and get the same error.

nodeLinker: pnpm
yarnPath: .yarn/releases/yarn-4.7.0.cjs

I'm seeing this too with nodeLinker: node-modules in a large monorepo when upgrading from 4.2.2 -> 4.8.0 (self hosted GH runners).

Edit: doesn't occur for me on 4.7.0. Will provide more details in a separate report when I can!

@MorrisonCole can you run yarn set version from sources --branch 6743 (#6743) and try again?

[MorrisonCole]

Hey @arcanis - thanks for taking a look so quickly!

Can confirm that we don't see the issue with #6743 🎉
