Bug report

Describe the bug

Hello, I just upgraded next from 9.3 to 9.4 today. It seems that compiling a single page takes too long. More than 3 minutes. Sometimes it never compiles too.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

Install next 9.4
run next dev and start the server
Go to any page in localhost:3000
It takes a very long time to compile and even it compiles, the page never loads on browser sometimes.

Expected behavior

It should compile the page faster (usually 5 to 10 seconds) and load the page.

For those curious, this was caused by Windows Defender. Windows Defender was delaying the HMR (to do a scan) because our emitted JavaScript files contained the word eval! That’s why macOS was unaffected.
