Comment:

 Hey @joomskys - thanks for the bug report and sample image.

 I gave your image a test on my server that has AVIF support enabled and
 the srcset entries were created, which means it is likely your server
 lacks AVIF support.

 Can you check to see if your media handling includes AVIF? Look under
 Tools->Site Health->Info->Media and check which media editor and formats
 are supported (search for "AVIF").

 I tested again on a site that lacks AVIF support and got the behavior you
 described - I was able to upload the image, but no subsizes were created.

 Interestingly, when I tried uploading the AVIF file in the Media library,
 I got an error message "This image cannot be processed by the web server.
 Convert it to JPEG or PNG before uploading." and the image refuxed to
 upload. So this does feel like a bug to me, the behavior should be
 consistent - the bug is likely on the Gutenberg (rather than core) side
 though - the editor should reject your AVIF file when you try to upload it
 on a site that lacks AVIF support.

 > am using siteground web hosting!

 Great, you can ask them about enabling AVIF for your site! It may be
 available only on certain plans or they may need to head from enough
 customers wanting it to add support.
