Manifest 5 Issue: Uncaught UxpRuntimeError and EvalError in console

[Karmalakas]

Error says you have inline script, which is no longer allowed. In Webpack you might have a setup, which uses eval - check this post:

Move Layer to Front through batch-play works differently in PS 23.4.1

Check for inline handlers – or, if you’re using webpack, check how your sourcemaps are being handled – default is to use eval – which will cause the issue. If you’re using webpack, you can (for dev purposes), add allowCodeGenerationFromStrings: true to your requiredPermissions section in the manifest, and the error should go away.
