我已经设置了一个 latex 序言，它可以生成我的自定义定理框，用于定义、定理、引理等。我从这里的某个人那里复制粘贴了它，并对其进行了轻微的修改，直到昨天，它在过去三年里一直运行良好。我随机开始收到将 itemize 环境放入我的定义环境中的错误。

\begin{izrek}
Naj bo $M$ $R$-modul. Naslednje tri trditve so ekvivalentne:
\begin{enumerate}
\item $M$ je prost.
\item $M$ je izomorfen (lahko tudi neskončni) direktni vsoti kopij kolobarja $R$.
\item $M = \bigoplus_{\lambda \in \Lambda} M_\lambda$, kjer je $M_\lambda \leq M$ in $M_\lambda \cong R.$
\end{enumerate}
\end{izrek}
\begin{definicija}
Naj bosta $M$ in $N$ $R$-modula in $F$ prosti $R$-modul
z bazo $X = M \times N$ (kartezični produkt množic).
Naj bo $T$ podmodul v $F$, generiran z naslednjimi elementi:
\begin{itemize}
\item $(m_1 + m_2, n) -(m_1, n) - (m_2, n)$ za $m_1, m_2 \in M$ in $n \in N$.
\item $(m, n_1 + n_2) - (m, n_1) - (m, n_2)$ za $m \in M$ in $n_1, n_2 \in N$.
\item $(rm, n) - r(m, n)$ za $r \in R$, $m \in M$, $n \in N$.
\item $(m, rn) - r(m, n)$ za $r \in R$, $m \in M$, $n \in N$.
\end{itemize}
$R$-modulu $\quot{F}{T}$ pravimo tenzorski produkt modulov $M$ in $N$ in ga
označimo s
$$\quot{F}{T} = M \otimes_R N.$$

环境“izrek”工作正常，但环境“definicija”在第 296 行给我一个错误“出了点问题——可能缺少 \item”。这是我遇到的唯一错误。这非常令人沮丧，因为过去几年成功编译的所有文档，每当我将 itemize 放入“definicija”环境中时，都会突然给我同样的错误。另一件事是错误无法重现——上面的代码在我的另一台电脑上运行良好。我尝试过几次卸载和安装 MikTeX，但无济于事。我迫切需要一个解决方案，任何反馈都将不胜感激。
