项目属性中的Eclipse错误

Question

我在我的Antergos（基于Archlinux的）操作系统上安装了Eclipse，我想更改项目的C/C++版本中的设置，但是当我尝试打开时出现以下错误：

。

该错误之后是Java异常（NullPointerException）。

我尝试更新Eclipse，但它已经是最新的。我也尝试重新启动应用程序并清理/构建，但无济于事。直到今天，我从来没有遇到过这样的问题。我想也许这是一个新的更新，但我找不到遇到同样问题的其他人。

这个错误是什么意思，以及如何解决它？

编辑：这里是.log文件的内容：

这个问题已经被报告如下：

https://git.eclipse.org/c/platform/eclipse.platform.swt.git/commit/?id=1a375bfbb7dca92b102db09891a18eeb80d671f2

我想的Archlinux用户似乎成为第一个看到它的人，因为Arch软件包总是处于最新版本并且最近更新了Gtk和Wayland图书馆。
