When applying any default/built-in shader via Fill → Shader OR Effects → Shader on the Figma desktop app, nothing renders on canvas and no shader panel appears for me. Confirmed via DevTools (⌥⌘I → Console/Network):
GET https://www.figma.com/community/custom_tool/28/code → 404 (Not Found)
[published-artifact-custom-resource] failed to load artifact data
XHR for "/community/custom_tool/28/code" failed with status 404
This happens across all built-in shaders (tested Risograph print and others), not just one. File is under a pro plan, full seat, so this isn't a plan/seat issue.
