On >3.41.0 dragging blocks in PTE gives "Can't upload this file here" error

[jorngeorg]

After upgrading to > 3.41.0 I get a "Can't upload this file here" error whenever dragging a block element in the PTE.
The error box doesn't go away. The only way to remove it is to reload the studio. See screen capture for behaviour:

Same in 3.42.0

Asked in Slack today... https://sanity-io-land.slack.com/archives/C9Z7RC3V1/p1716322030051909

Yes, same on all > 3.41.0 versions. We've downgraded all studios and will not upgrade until this as been addressed.

I'm also getting reports of the following warning appearing as a toast when moving blocks. Which might be relatable?

Could not validate the resulting portable text to insert. Editor value must be an array of Portable Text blocks, or undefined. Try to insert as plain text (shift-paste) instead.

As a sidenote, I'd suggest not showing such technical errors to the user as it doesn't really make any sense to editors and only create fear and concern for the product.

Let me know if you need more information to triage this issue. Happy to help out with any information if needed.

This should be fixed in #6867 and was a part of the v3.46.0.
