引用变成了问号，除非我重新启动 Latex

Question

我已经设置了我的围兜如下

% The following statement selects the style to use for references.  It controls the sort order of the entries in the bibliography and also the formatting for the in-text labels.
\bibliographystyle{plain}
% This specifies the location of the file containing the bibliographic information.  
% It assumes you're using BibTeX (if not, why not?).
\cleardoublepage % This is needed if the book class is used, to place the anchor in the correct page,
% because the bibliography will start on its own page.
% Use \clearpage instead if the document class uses the "oneside" argument
\phantomsection  % With hyperref package, enables hyperlinking from the table of contents to bibliography             
% The following statement causes the title "References" to be used for the bibliography section:
\renewcommand*{\bibname}{References}

% Add the References to the Table of Contents
\addcontentsline{toc}{chapter}{\textbf{References}}

\bibliography{Bibs/vaccination_references,Bibs/ml_references}


% Tip 5: You can create multiple .bib files to organize your references. 
% Just list them all in the \bibliogaphy command, separated by commas (no spaces).

% The following statement causes the specified references to be added to the bibliography% even if they were not 
% cited in the text. The asterisk is a wildcard that causes all entries in the bibliographic database to be included (optional).
\nocite{*}

我将我的 bib 拆分成多个 bib，以便更容易跟踪更改。当我\cite{}在第二个 bib 中使用引用时，它总是显示为问号，直到我关闭并重新打开 Texstudio。

知道为什么会这样吗？

我只能谈谈 Texmaker 和 Adob​​e Acrobat Reader。如果 Adob​​e Acrobat Reader 打开一个文件，它会锁定它，这与基本的记事本不同。这意味着，如果您运行 pdflatex 或类似程序，就会出现错误。
但是：Texmaker 有这个特殊功能，即“快速构建”功能可能会中断。如果您运行“快速构建”，则必须单击“查看 PDF”才能看到它。在某些情况下，循环会产生错误、无限循环、无限输出（由于无限循环），Texmaker 也可能发生这种中断。

由于我使用了很多循环，所以这种情况经常发生。
