Toggle Side Panel button is missing

[Codelime]

After updating my local from 6.5 to 6.5.12, my Toggle Side Panel button is missing from the top left when trying to edit pages. Is this a known issue and is there a solution for getting this back? Instead of this...

I get this...

The Console log shows this...

@Codelime I am using 6.5.12 and there is no issue. Generally you don’t see Toggle Side Panel button when page doesn’t load completely. You can verify error.log also.

I remember facing something similar and the issue was the version of Core Components that was installed in the instance.
