This time I do not get a blank page when I run the editor but when I check any of the tabs (experiments, algorithms) etc I get a blank page. It happened in the middle of editing some experiment but I do not know where is the problem because the experiment is running.

I get this error on the firefox console:

too much recursion[Learn More]

and this error on the terminal:
