I see that you have @playwright/test and playwright installed. You don't need to have playwright installed, the @playwright/test package is enough. Could you try the following?

npm uninstall playwright
npx playwright test --ui

Also it seems like you still are on the old version - npx playwright --version should confirm that. Try deleting the node_modules folder and running npm install again.

I hadn't changed anything. It was working last night, broke today. Now working again upon removal and reinstall. Thanks none the less
