Hello,
I am trying to edit the theme code on a dev store and I get a blank page. Been trying for more than 30 mins and the theme editor does not load.
Please check.
Same issue here. Another day, another broken Shopify feature 
My team is also facing the same issue since last 10 hrs. The theme editor does not load at all.
Hey @Jonida_Mersinllari , thanks for reporting this. It appears the theme code editor appearing blank is another symptom of the theme editor issue reported earlier today (1, 2).
The relevant internal team is aware and investigating the root cause - apologies for the inconvenience and thanks again for reporting the issue here. We’ll follow up here once a fix is in the works.
Hi folks - update on this: the team are working on a fix now. Will post here once it’s shipped.
