Problem: I use a one-click icon to do everything from platex-to-pdf for a multiple paths of compilation, dvipdfmx, upbib. I have label, ref and bibliographystyle in .tex. I use SumatraPDF for displaying pdf.

I encounter the error message in the second dvipdfmx saying,

DVI ID = 37 dvipdfmx:fatal: Something is wrong. Are you sure this is a DVI file? Output file removed.

Still the process continues and somehow looks to produce .pdf.
I would like to know the cause of this error and fix it.

Related Bug Report: There is the similar bug report "xdvipdfmx:fatal: Something is wrong. Are you sure this is a DVI file?", but that resolution does not quite match my case because I do not mix up texlive versions at all. I use only texlive2018.

Environment:
TeXstudio: 2.12.14
Qt: (I do not know ! )
OS: Windows10
TeX distribution: texlive 2018

Expected behavior:
It is a bit strange that the second running of dvipdmfx has no output just below its starting output of its name, like:
開始されたプロセス: dvipdfmx.exe "xxxxxx".dvi
開始されたプロセス: platex.exe -synctex=-1
At this point of processing, it might be like that a C compier spawns its child processes in parallel. I am not sure but I doubt that running tools in a order would be executed incorrectly.

Actual behavior ( Sorry for some Japanese messages included):

How to reproduce:

It is rather hard to provide the original .tex file as is because this is a part of academia paper. The copyright is already transferred to the academia scoiety.
