 Replying to [comment:2 celloexpressions]:
 > I cannot reproduce this error on a clean install of WordPress 5.7. Can
 anyone else reproduce this behavior? There are likely other details in
 your setup that trigger the issue @stfa76 - are you able to identify any
 specific plugins or other information that may relate to this issue?
 Yes, I was able to reproduce this 100%, even with WordPress 5.9.3. I know
 it's an old ticket, but I stumbled here from Google and wanted to share my
 resolution. I was experiencing 1:1 the same behaviour as the OP.

 It was a result of php-gd not being installed on my system. I rectified
 this on a Ubuntu install, for example, with:
 {{{
 apt-get install php-gd
 }}}
 and then restarted my webserver. After doing this, I could resize images
 and change the favicon (regardless of whether it needed to be resized or
 not).

 Thanks to this site for pointing me in the right direction:
