我有一份长达 40 页的文档，大部分内容运行良好，但到最后开始在不同的行上出现大量错误。该文档总共有 42 个错误，发生在几行上，一行通常有 10-15 个错误。该文档编译正常，看起来也符合预期，但我仍然对出现错误感到困扰，以及为什么会出现这些错误，因此非常感激您的帮助。
根据评论的要求，我简化了文档以便在此处分享，现在它看起来像这样：

此版本有 13 个错误，全部位于第 47 行（该\clearpage行）。以下是我收到的错误：
! Undefined control sequence.
\bbl@fixname #1->\begingroup \def \bbl@tempe
{l@}\edef \bbl@tempd {\noexpand...
l.47 \clearpage
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
! Argument of \bbl@tempd has an extra }.
<inserted text>
\par
l.47 \clearpage
I've run across a `}' that doesn't seem to match anything.
For example, `\def\a#1{...}' and `\a}' would produce
this error. If you simply proceed now, the `\par' that
I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.
Runaway argument?
{\noexpand \@ifundefined {\noexpand \bbl@tempe \languagename }}\bbl@tempd \ETC.
! Paragraph ended before \bbl@tempd was complete.
<to be read again>
\par
l.47 \clearpage
I suspect you've forgotten a `}', causing me to apply this
control sequence to too much text. How can we recover?
My plan is to forget the whole thing and hope for the best.
! Use of \begingroup doesn't match its definition.
<to be read again> ...MAGYAR{{1}}\begingroup \def
{L@}\edef \par
l.47 \clearpage
If you say, e.g., `\def\a1{...}', then you must always
put `1' after `\a', since control sequence names are
made up of letters only. The macro here has not been
followed by the required stuff, so I'm ignoring it.
! Missing { inserted.
\MakeUppercase ... {\uppercase {#1}}\reserved@a }

Where was the left brace? You said something like `\def\a}',
which I'm going to interpret as `\def\a{}'.
! Missing } inserted.

I've inserted something that you may have forgotten.

With luck, this will get me unwedged. But if you
really didn't forget anything, try typing `2' now; then
my insertion and my current dilemma will both disappear.

I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'.

To put a horizontal rule in an hbox or an alignment,
you should use \leaders or \hrulefill (see The TeXbook).

A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)

Dimensions can be in units of em, ex, in, pt, pc,
cm, mm, dd, cc, nd, nc, bp, or sp; but yours is a new one!
I'll assume that you meant to say pt, for printer's points.
To recover gracefully from this error, it's best to
delete the erroneous units; e.g., type `2' to delete
two letters. (See Chapter 27 of The TeXbook.)

不确定这是否重要，但我正在在线编辑器中写作（overleaf）。

您应该在使用该选项fancyhdr之前加载（如语言定义文件发出的警告所指示的那样）。然而，这在某种程度上与 相冲突。babelmagyar\MakeUppercase
您可以重新定义\sectionmark以避免这种情况，或者textcase使用该overload选项加载。

我也做了一些更改：我删除了所有地方的选项pdftex，通常不应该使用它；t1enc最好加载而不是 ；如果使用 ，fontenc加载是无用的；包含在最新版本的 LaTeX 中；由 加载。colorxcolorfixltx2eurlhyperref
