Microsoft Edge Dev regression: apphelper.exe missing

After updating to 147.0.3878.0, apphelper.exe is missing. Can no longer use installed apps, or install new ones.

I copied the program from the most recent update folder and it's working. But clearly the most recent Edge Dev update deleted it from the main program folder.
