重新安装Unity 2021.3.4f1编辑器后项目无法正常构建的问题求助

我之前有个项目构建完全正常，但后来不得不重新安装Unity，并且下载了我之前使用的特定版本编辑器（2021.3.4f1）。现在我的项目要么构建失败，要么构建完成后场景出现画面抖动的异常情况。一开始我以为是某个场景文件损坏，替换之后才发现，那些从八月份起就没改动过、之前构建完全正常的旧分支版本也出现了构建问题。

我已经尝试了以下操作：

• 替换疑似损坏的场景，但没有效果，构建后的场景依然抖动甚至会崩溃
• 打开之前确认没问题的旧分支版本，有的直接构建失败，有的同样出现画面抖动问题，还有的是其他场景出现异常

控制台输出的错误信息如下：

Unity构建核心错误 #

尝试用新版本编辑器打开项目的错误 #

后来我尝试用新版本编辑器打开这个项目，结果只能以安全模式打开，还出现了2个致命错误：

• Assets\Oculus\VR\Editor\OVRDeviceSelector.cs(45,20): error CS1061: 'OculusSettings' does not contain a definition for 'TargetQuest' and no accessible extension method 'TargetQuest' accepting a first argument of type 'OculusSettings' could be found (are you missing a using directive or an assembly reference?)
• 提示Unloading broken assembly Library/ScriptAssemblies/Unity.Rider.Editor.dll, this assembly can cause crashes in the runtime

ADB相关错误 #

另外还出现了ADB的错误提示：

Multiple ADB server instances found, the following ADB server instance have been terminated due to being run from another SDK. Process paths:
C:\Program Files\Unity\Hub\Editor\2021.3.4f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\platform-tools\adb.exe

现在我有点懵了，想问问大家，是不是我现在用的这个2021.3.4f1编辑器本身有问题？
