I have downloaded etcher for Windows and am receiving an error message when everytime I try to flash from file. The file I am trying to flash is a large (umbrelos installer). I have uninstalled and reinstalled the program and the did not work. I have tried to flash the file as the administrator and it did not work. Any suggestions will help?

Yes, it is a VERY common issue! Fortunately there is a simple robust solution. Go to Settings \> Apps & Features. Locate BalenaEtcher. Click uninstall. Then use raspberry pi imager.
