After the popup that announced Composer 1.5 the build button on plans stopped working, had to use agent mode, reference the plan and tell it to execute it, it did not matter which model I picked, the button did nothing on click.
Steps to Reproduce
Make a plan, save it to the repo, then try to build it.
Hey, thanks for the report. This is a known issue where the Build button in Plan Mode stops responding. We got a similar report a couple of days ago: Build button not responding. The team is aware.
A couple of workarounds:
Open a new chat and run the plan again. Check if Build works in a fresh session.
After the plan finishes, reload the window (Ctrl + Shift + P → “Reload Window”), then try Build again.
Also, can you share the Request ID from that chat? (Chat menu in the top right → Copy Request ID). And does this bug happen every time for you, or only sometimes?
I have the same problem.

It happens in all attempts to click the build button regardless which plan I have open. I tried even opening a new chat and seeing if the build button would work then, but it didn’t. Here’s my RequestID from the chat I built the plan in: 97cf0dac-6e79-464e-a9a1-9a3c941f79f6
