How to use webpack V5 in yarn start

[raix]

Did you remove node_modules folder and re installing?

I have the same issue, I tried upgrading to v5.0.0 but I then got a JS out of memory exception. So I removed my package-lock.json and deleted the folder node_modules manually and I ran npm i from scratch. I am also now getting this same error, on npm run start on npm run build and on all CI/CD pipelines. Any ideas?

do you have node_modules out side the project folder?

[fkocovski]

Nope same level as src, public and where package.json is

What output do you get when running npm why webpack?
(same question if you use yarn, yarn why webpack)
