Thanks for reporting this @dzgierski19!

Haven't seen that error before. Might be related to the new version of yarn? Your instance seems to be upgrading to 4.0.1 automatically, but SE2 should use yarn 3.2.3, which is included locally (inside /.yarn/releases/)

Could you run yarn --version inside the scaffold-eth-folder.

Could you also remove all node_modules folders (root, hardhat, nextjs), run yarn cache clean and then yarn install again... and see if it works?
