As show below, as long as Show Text node is muted, everything works fine.
However, when the node is activated, running the workflow makes Media Assets and Job Queue go blank.
Refreshing the browser doesn't help and they remain empty until restarting comfyUI.


I intentionally picked the simplest workflow as an example, but observed the same problem with workflows for SDXL, ZImage, Flux.1 and 2 models in native and gguf formats.
It started since the last update to ComfyUI 0.16.4 and I think it might be related to the issues reported below:
