Research direction
Start with extensions-builtin/sd_forge_spectrum/lib_spectrum/forecaster.py at line 21 and reproduce the failure by enabling Spectrum Integrated and a ControlNet unit such as Canny before clicking Generate. Trace why _taus receives a None t_max in that combination. Done means generation no longer raises the reported TypeError with Spectrum and ControlNet enabled.
