Android studio 编译颤振应用程序时出错

我正试图在android studio 3.5版本中运行我的颤振应用程序，但我无法做到。我升级了Flitter并重新安装了android studio。我使缓存失效并重新启动，但没有解决我的问题。我尝试使用VisualStudio代码，但得到了相同的错误。下面你可以看到我得到的错误

有人知道如何解决这个问题吗？我的android studio以前工作得很好，但不确定这是在更新之后还是什么

FAILURE: Build failed with an exception.

首先，在cmd中检查你的颤振医生，看看一切正常，然后，当你在android studio中创建一个新的颤振项目时，默认情况下不要使用kotlin或java作为lenguague，不要在它们上标记任何内容，只是让它们为空
