One reason could be a non-utf8 character in the file. This would result in a log message similar to

JSON::GeneratorError : source sequence is illegal/malformed utf-8

From the Linux command line, this command will show lines containing non-utf8 characters

grep -axv '.*' file.txt

where file.txt is replaced with myview.lkml , for example.

Another possible reason you should keep in mind is browser extensions, especially Add blockers like ABP can prevent a file from being loaded. This usually happens if the file contains dimensions/measures related to advertisement or ads.
