TD 2025.32820, macOS — python creating a Light COMP after a Time COMP -> TD hangs forever

Hi,
TD 2025.32820, macOS (Apple Silicon)

Once an explicit Time COMP has been created in the project during the session,
creating a Light COMP anywhere in the project permanently deadlocks the main
thread. The UI freezes, FPS drops to 0, and the process must be force-killed.
The hang happens inside the Light COMP’s create. Reproduced on a fresh default
project across 6+ independent instances.

Min repro:

op('/project1').create(timeCOMP, 'time1')
op('/project1').create(lightCOMP, 'light1')   # never returns

Boundary conditions (each tested on its own fresh instance):

  • Reverse order (Light first, then Time) — OK.
  • Light COMP alone, no Time COMP (project still has the default /local/time) — OK,
    so the default timeline is not the trigger; an explicit timeCOMP operator is.
  • Time COMP created then DESTROYED, then Light COMP — still hangs (destroying the
    Time COMP does not clear the condition).
  • Time COMP at /project1, Light COMP inside a child COMP — still hangs (project-wide,
    not network-local).
  • Time COMP then Camera COMP / Ambient Light COMP / Constraint / Handle / Actor /
    Force / Constant CHOP — all OK. Only the standard Light COMP (point/cone/distant)
    hangs.

Best,
Alex
