I started to get a server error while running snapshot

I started to get a server error while running snapshot and was able to narrow it down to the dynamik-builder in the wp-contents/uploads folder. that folder is automatically generated by Dynamic Website Builder.

I dragged the folder out temporarily - and the snapshot succeeded.

I was just curious as to what caused the error (because there are non-graphic files?/php files?) and wondering if there was a fix.
Error screenshot attached.
