React Native start failed with error code -4094 how to solve this ONCE for ALL?

Question

I'm trying to run react-native start (as all the other days, it works normally) and it gives me this error:

THE ERROR

WHAT I'VE TRIED

Deleted node_modules packages and package-lock.json and run npm install. It still fails after many trials
Update node.js to the latest-recommended version: 12.16.3. Then repeat the above step and it still fails
Run npm cache clean ( gives error) and reapeat step 1 --> Fail
EDIT 1 I have tried react-native start --reset-cache and it gives the same error
EDIT 2 I've tried: npm cache clean --force and it gives me error:

PLEASE HELP ME

Have you tried clearing your Metro and react-native caches? Try watchman watch-del-all && react-native start --reset-cache — Abe
I think it might be a permission issue that is preventing as your error log shows at line 11. Check the permission. — Yogesh Aggarwal
Thanks for the comment @Yogesh. Can you please tell me what is that permission for and where can I check it? — Mark

Looks like the issue is with the npm cache. Try the following solution:

Run the command: npm cache verify

If you get errors then run: npm cache clear --force

Right Click on C: > Properties > Tools Tab.

Select Check or Check-now under Error Checking menu.

Reboot your PC after the process is completed.
