You need to check your PHP error log and try some of the options to reduce your export size in case your PHP memory limits are being exceeded.

Thanks for providing those lines from the error log – however, none of them are a “fatal” error which would result in a white screen – please search the whole error log for the term “Fatal” and provide anything that you find here.
Closed as no follow up from OP.
