Error while opening discover for updating

Im having the next error when opening discover, im using also fedora 44:

(sorry for the error msg in spanish)

“Ha fallado al cargar primary caché para repo “updates” desde “/var/cache/PackageKit/44/metadata/updates-3cc07c89a20302f2/solv/updates.solv”: read error while reading strings”

I can update with dnf without problem. ¿How can I solve this error?

Thanks!
