Error writing SD card

When running balenaEtcher I get the following error message. No way it will work.
Note I used the img file after decompression by iZArc, not the gz archive directly in balenaEtcher.
Then I tried compressed, decompressed, redownloaded etc… no way, always the same message.
File is confirmed OK.

Got it: balenaEtcher needs to be started as administrator even though the user who uses it, is an administrator. Is this a Windows 11 thing?
