Kotlin中出现未知错误：kotlin.NotImplementedError：仅在JetBrains的分叉版本中实现，有人能帮我解决吗？

我在Kotlin项目里遇到了一个自己也不太清楚原因的错误。
这个项目原本可以跑着，但后来我在另一台电脑上克隆了一份，结果在那台电脑上出现了下面这个错误：

我需要解决这个错误，但不知道该怎么做；如果有人曾经遇到过这个错误和/或知道如何处理，我愿意采纳他的建议！

注：这是一个学生项目，因此如果有些地方不完美也很正常，通常它是可以跑通的

解决方案

这是Compose Multiplatform的一个已知问题：
https://youtrack.jetbrains.com/projects/CMP/issues/CMP-8617

在那里有人提出了建议...

请使用 org.jetbrains.compose.ui:ui-util (1.10.2) 包。

这很可能是JetBrains的一个分叉，不在 androidx.compose.ui.util 包中。
