Can you try to update only VichUploaderBundle and see what happens?

Yup... doing composer update vich/uploader-bundel without updating the dependencies...

Hmmm... doing the composer update symfony/* also without updating any other dependencies...

... also works like a charm.

Even after updating api-platform with composer update api-platform/* (without dependency update with --with-all-dependencies), upload works.

Looks like the trouble might be caused by any "subsequent" dependency updated when using --with-all-dependencies. Have to investigate further...

O.k... when it comes to doctrine/* updates in the course of doing composer update trikoder/oauth2-bundle --with-all-dependencies, then the problems begin...

Downgrading doctrine/inflector (1.4.3 => 1.3.1): ❌
Downgrading doctrine/common (2.13.3 => 2.12.0): ❌
Downgrading doctrine/orm (v2.7.3 => v2.7.2): ✔ --> Starts working again!

Suspect found... doctrine/orm v2.7.3... but why? Maybe somthing for the doctrine/orm issue list?

Hmmmm... worth to try out/check... thanks a lot @garak

O.k... seems to be my fault... or an inattention. As stated in the embeddable tutorial a basic @Column mapping, i.e. @Column annotations must be given in the embeddale class definition, which in my case were dropped by mistake (using a derivated embeddable class to do some API-Platform specific annotation complements). Weird, that it worked in v2.7.2... but this might be related to the PR referenced above. For the sake of completeness here what I've changed:
