Not sure when exactly this started to happen, but I now get broken images on my site - for example

According to the console, the original attachment is suffixed with -resized but I do not see a corresponding file, so the render fails.

/assets/uploads/files/1656084919400-blurred-resized.png does not exist, but /assets/uploads/files/1656084919400-blurred.png does.

Any ideas? Currently running 3.8.3.

Whilst not the same topic, there seems to be a relationship in the form of resized with this topic
