[Bug Report]: pitcher message time out error

[ErKeLost]

When using the SDK's browser session, I often encounter errors while writing code, causing the entire project to run incorrectly. Why is this happening? This leads to a poor development experience.

Uncaught (in promise) Error: null: Pitcher message fs/writeFile timed out
    at browser.js:1057:17

Is this a network issue? We are very worried about the overall usage of future users. Can this problem be solved by setting up or modifying the CDN?
