OSError: [Errno 30] Read-only file system: 'dbt_packages'

[dfv-ms]

Expected behavior

I'm using vs-code on MacOS 15.7.3. I've set up a custom python environment /Users/username/source/python/dbt/dbt-env for dbt and registered the path in vs-code.

I expect to run this dbt instance from vs-code

Actual behavior

Since version 0.59.0 (and 0.59.1) I get an error OSError: [Errno 30] Read-only file system: 'dbt_packages'. For details see below.

Using version 0.58.13 everything is fine.

Steps To Reproduce

I open a model and press shift-cmd-enter. The dbt processing starts and runs into the above error.
