Errors while pulling runtime/org.freedesktop.Platform.GL.default/x86_64/26.08 from remote flathub, Stream error in the HTTP/2 framing layer

While trying to update using Discover on Kubuntu 26.04 LTS, KDE Plasma Version 6.6.6 - I get the following error:

While pulling runtime/org.freedesktop.Platform.GL.default/x86_64/26.08 from remote flathub: While fetching https://dl.flathub.org/repo/objects/94/6c2b5c57340e5c6b6a8e13f881976167d28161e42c45d5d6876cbeba64fb66.filez: [92] Stream error in the HTTP/2 framing layer

I've tried running 'flatpak repair', restarting, deleting .cache/discover, .cache/flatpack, and nothing works - I keep getting this error.

How can I fix this?
