Do you know about the AndroidManifest.SetFixedWindowSize error?

I am able to build the apk with no problem, but when I change the FullscreenMode to Windowed and build, I get an error.
The error is as follows

NullReferenceException: Object reference not set to an instance of an object
SetFixedWindowSize (System.String activity, System.Int32 defaultWidth, System.Int32 defaultHeight, System.Int 32 minimumWidth, System.Int32 minimumHeight) (at <04fd49fe433b413dbaa78a3164f6959b>:0)

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)

As far as I can see, it looks like AndroidManifest?
Speaking of AndroidManifest, it is rather common for multiple AndroidManifests to collide with each other and cause errors, or errors due to lack of permissions, but the fact that a NullReferenceException occurs at the build stage makes no sense at all. I don’t understand it at all.

I am sure that it has something to do with the screen size, since it says “SetFixedWindowSize” and I can build by undoing the FullscreenMode setting, but I don’t know what the error text means, and I can’t find any information about it in a search, so I can’t solve it.
If you know anything about this, please let me know.
