Is there a known bug in the newest update Copilot APP version 157.0.4341.60? The 157.0.4341.60 version will not submit queries on my WIN11 Home laptop- the UI is fully functional except for the "send" function, including "Send Feedback". Details, including versions below:

There is no public Microsoft advisory confirming Copilot version 157.0.4341.60 as a known gray-Send-button issue, so the most appropriate next action is to repair or reset its local state and, if that fails, perform a clean uninstall and reinstall.
Similar Copilot send/UI failures have been reported after updates, but the reports do not match your exact build and symptoms closely enough to establish a version-wide regression.^1^
Your Get-AppxPackage result is expected to be unhelpful for an EXE-installed application; use Installed apps instead.
Windows only displays Repair, Reset, or Advanced options when the application’s installer supports them.^2^
Reset warning: Reset removes local application settings and cached state. Your server-synchronized chat history should reappear after sign-in, but preserve any unsynchronized local material first.
If Advanced options, Repair, or Reset is absent, proceed directly to reinstalling.
copilotapp, copilotapphost, and WebView2 child processes are no longer holding files or cached state.Microsoft documents this uninstall path and Microsoft Store reinstall method specifically for Copilot on Windows.^3^
After reinstalling, verify that the executable version changed—or that the same version now works with newly created local state:
$process = Get-Process copilotapp -ErrorAction Stop |
Select-Object -First 1
$path = $process.Path
(Get-Item $path).VersionInfo |
Select-Object ProductVersion, FileVersion
That result would favor an application-build or service/client compatibility defect over corrupted local state, particularly because Edge Copilot works with the same account.
Report it through Feedback Hub, rather than Copilot’s nonfunctional feedback control:
winverFeedback Hub supports screenshots, diagnostic recordings, attachments, similar-report matching, and marking a problem as blocking.^4^
Your current evidence does not establish an authentication, keyboard, or missing-WebView2 problem, so repeating those checks is unlikely to discriminate further. Continue using Edge Copilot as the temporary workaround while the desktop report is investigated.
