:lady_beetle: Provide a clear description of the bug
When trying to open a DevContainer project using Cursor, the process gets stuck.
Containers work fine, my app is working, but IDE is stuck. I cannot do anything with code, and in the left corner, there is info “Setting up Dev Container (details): Starting Dev Container…”.

When I click “details” I see this info:

2025-10-29 08:19:11.701 [info] [devcontainer run-user-commands]: {"type":"text","level":2,"timestamp":1761722351701,"text":"Writing docker-compose.devcontainer.containerFeatures-1761722351701-42b499be-8ae1-4f5c-ba56-f42520c5fb32.yml to /tmp/devcontainercli-wronecki/docker-compose"}

When I run this last command in a separate terminal, then everything just confirms that containers work fine.

Steps to Reproduce

I cannot say, because the same project is working well on my second PC with similar settings. And I already tried to reinstall IDE.

Does this stop you from using Cursor

Yes - Cursor is unusable
