Comment (by azaozz):

 @subrataemfluence @Blamedutchie could you look in the browser tools
 "Network" tab for the returned value from the server when you see these
 JSON errors. Any unexpected output from PHP may cause therm, could perhaps
 be coming from something else like PHP notices, etc.

 Looking at
 https://github.com/WordPress/gutenberg/issues/8935#issuecomment-466306820,
 this is the same old problem with creating image sub-sizes. Large images
 take a lot of time and server resources to process/resize. Currently all
 sub-sizes are created in the same PHP run. That often fails on low powered
 servers or web hosting accounts with restricted resources.

 There is a ticket and a patch to fix this by separating the creation of
 image sub-sizes, #40439. If the failures are caused by the same issue,
 perhaps this should be closed as a duplicate.
