V11 Print Format Builder Not Loading

I just installed a new implementation of ERPNext V11 from scratch. I’m going through setting up my site and settings, etc., there appear to be no errors and it’s running great, however, if I try to go to the Print Format Builder - I get a header and nothing else… .just a blank white screen (see image).

I’m using Chrome and my previous instance (separate VM) of V10 seems to load the print format builder without issue.

where should i start with diagnosing this?

Just found this thread:

Trying this fix now and will update with results.

Fixed using bench update… thanks!
