As a newcomer to React, I decided to incorporate Material UI components into my project. After installing the components locally using npm install and importing them into my project, I encountered an error when trying to run start:

Error: Invalid hook call. Hooks can only be called inside of a function component body. This error could stem from several reasons:

• Possible mismatching versions of React and the renderer (such as React DOM)
• Violation of the Rules of Hooks
• Presence of multiple copies of React within the same app

For tips on debugging and resolving this issue, visit https://reactjs.org/link/invalid-hook-call. ▶ 22 stack frames were collapsed. Module. src/index.js:7

Despite researching common solutions for this error, such as checking for duplicate React installations by running npm ls react, I was unable to resolve the issue. Upon finding multiple copies of React in my project directory (as shown in the terminal screenshot), I assumed that "deduped" meant deduplicated and hence not the root cause.

Interestingly, removing the problematic component resolved the error instantly. If anyone has insight on solving this issue, I would greatly appreciate it.
