Executing the 'deopt' related script will output a large amount of useless logs in macos platform

[champkeh]

I clone the project and install dependencies, then run this command:

pnpm run deopt

the console keeps outputting a lot of logs

After I manually created a profile directory in the root project directory, then re-execute the above command, it works

Thanks, I had a similar problem where a significant number of logs were generated. After creating a directory in the profile folder in the root directory, the issue was resolved.
