Application Deploy Exception

Trying to deploy the template Meadow project app and got error. Log:
1>------ Deploy started: Project: MeadowApplication1, Configuration: Release Any CPU ------
1>[24.11.2020 1:05:02] Deploying to Meadow on COM4…
1>Exception of type ‘MeadowCLI.DeviceManagement.MeadowDeviceManagerException’ was thrown.
========== Build: 0 succeeded, 0 failed, 1 up-to-date, 0 skipped ==========
========== Deploy: 0 succeeded, 1 failed, 0 skipped ==========

When trying to update Meadow.OS got error:
[24.11.2020 1:16:28] Begin ‘Flash Device’
[24.11.2020 1:16:28] Upload Meadow.OS.bin (~2 mins)
[24.11.2020 1:17:41] Initialize device (~30s)
[24.11.2020 1:17:48] An unexpected error occurred. Please try again.

any suggestions?

I get the same error when deploying various sample projects.
I was able to deploy the HelloMeadow sample project successfully without error.
I then tried to deploy the Simon project and received the error below.
Now when I go back and try to deploy the HelloMeadow sample project, I continue to get the MeadowDeviceManagerException error, though the app is deployed and runs successfully.
Tried re-flashing the Meado.OS… didn’t help.
