You should replace this code in TaskDatabase.kt file
synchronized(this){
val instance= Room.databaseBuilder(
context.applicationContext,
TodoDatabase:: class.java,
DB_NAME
).fallbackToDestructiveMigration().build()
It will Solve the debug problem.

I am trying to have my code display the user's name at login in the home page, I can successfully move in from one activity to the next with a click, but when I add the recycler view in my home activity, it doesn't work. Attached is the recycler view XML, adapter activity, and my home class activity along with the log.

In your imports there are multiple UI's imported. Just check once where the recyclerview lies actually.
import kotlinx.android.synthetic.main.activity_main.*
import kotlinx.android.synthetic.main.recycv1.*
import kotlinx.android.synthetic.main.sidebar.*

you've not initialized the recyclerv_view in the activity class.

this is full error in app

Change the parameter type in
override fun onPostExecute(result: Void)
to
override fun onPostExecute(result: Void?).
And as Akhilesh Kumar mentioned here you should also change
class SaveThisImage : AsyncTask<Void, Void, Void>()
to
class SaveThisImage : AsyncTask<Void, Void, Void?>()
This is because the doInBackground in your code returns a nullable type Void?. The return value of doInBackground is passed as an argument to onPostExcecute but your onPostExecute accepts a non null value Void instead of a nullable one Void?.
As a side-note you should use Unit instead of Void when in Kotlin
EDIT
To make your saved image appear the media database needs to be updated. The media database is updated when you restart your device or after some time passes it will show up in the save location. To update the media database immediately you can use the MediaScannerConnection object.
Try passing your saved file to this function after bitmap.compress and pass your myImageFile
/**
* Updates the Pictures gallery to include the newly created file.
* #param fileObj: file path to be scanned so that the new file will appear in the gallery
*/
private fun refreshPhoneGallery(fileObj: File)
{
/* Scan the specified file path so that the new file will appear in gallery */
MediaScannerConnection.scanFile(
yourContext,
arrayOf(fileObj.path),
null,
object : MediaScannerConnection.OnScanCompletedListener
{
override fun onScanCompleted(scannedFilePath: String?, p1: Uri?)
{
// Do whatever
}
}
)

This question has already been asked, please see: You cannot start a load for a destroyed activity in relativelayout image using glide
In conclusion, instead of using "this" in your activity
Glide.with(***this***).load(data[0].team).into(ivHome_detail)
ivHome_detail.visible()
change "this" to "getApplicationContext" like so:
Glide.with(***getApplicationContext()***).load(data[0].team).into(ivHome_detail)
ivHome_detail.visible()
