Question

there is an Unwanted blank page before title in Latex, and I don't understand why there are string "_result_result" in this blank page, I am pretty sure I didn't add them

Answer 1

Please don't ignore the errors and warnings in the .log file. they exactly tell you which of your package are incompatible and which commands are missing.
To summarise the changes:
lots of incompatible packages
syntax errors in \titleformat. In particular you must not write \titleformat{}{}
writing \textbf some text is wrong. It is a macro so you either need \textbf{some text} or \bfseries some text
you should clean up your preamble, many of the packages are redundant, make no sense or are loaded multiple times.
% !TeX TS-program = xelatex
