使用 tkz-euclide 制作的三角图可以在 TeX Live 2018 中渲染，但不能在 2020 中渲染

我有一个三角形图，可以在 Overleaf（TeX Live 2018）中完美编译和渲染：

以下是编译成功的代码：

但是，如果将 TeX Live 发行版从 2018 更改为 2020，它会破坏图表并无法渲染：

我从中学到此主题不应\usetkzobj{all}与最新的 tkz-euclide 一起使用。在 2020 发行版中注释此行可修复部分问题，但并非全部问题。

以下是我的 Overleaf 项目的链接，希望对您有帮助：

背面 MWE

您可以尝试通过转到菜单 > TeX Live 来更改版本，然后查看会发生什么。（\usetkzobj{all}如果您将 TeX Live 切换到 2018，请记住取消注释，否则图表将无法正确呈现。）

有什么想法可能导致不兼容吗？谢谢！

\tkzDrawXXXX 的语法似乎已更改，这会影响您的\tkzDrawAltitude。此处编译：

\documentclass{article}
\usepackage{tkz-euclide}
\begin{document}
\begin{tikzpicture}[scale=0.5]
\tkzDefPoint(0,0){A}
\tkzDefPoint(12,0){D}
\tkzDefPoint(12,6){E}
\tkzLabelPoint[below right](D){$D$}
\tkzLabelPoint[above right](E){$E$}
\tkzLabelPoint[below left](A){$A$}
\begin{pgfinterruptboundingbox}
\tkzDrawSegment(A,D)
\tkzDrawSegment(A,E)
\tkzDrawSegment(D,E)
\tkzDefPoint(9,4.5){C}
\tkzDefMidPoint(A,E)\tkzGetPoint{C}
\tkzDrawAltitude(A,C,D)%<--- changed
\tkzGetPoint{B}
\tkzLabelPoint[above](C){$C$}
\tkzLabelPoint[below](B){$B$}
\tkzLabelSegment[right](B,C){$y_1$}
\tkzLabelSegment[right](D,E){$y_2$}
\tkzLabelSegment[below](A,B){$x_1$}
\tkzLabelSegment[below](B,D){$x_2$}
\tkzLabelSegment[above](A,C){$z_1$}
\tkzLabelSegment[above](C,E){$z_2$}
\tkzMarkRightAngle[size=0.75,opacity=.4](A,B,C)
\tkzMarkRightAngle[size=0.75,opacity=.4](A,D,E)
\draw[{Bar[width=3mm].Latex[]}-{Latex[]Bar[width=3mm]}]($(D)-(0,1.5)$) -- node [fill=white] {$l$} ($(A)-(0,1.5)$);
\end{pgfinterruptboundingbox}
%\draw (current bounding box.south east) rectangle (current bounding box.north west);
\end{tikzpicture}
