Database error on Kobo sice firmware 4.38.21908

[Erik Stel]

Kobo updated the firmware to version 4.38.21908 on 22-aug-2023. Since that update Calibre gives an error that the database is not supported. Working on Windows and with a Kobo Sage.

calibre, version 6.26.0
WARNING: Failed: Kobo database version unsupported - See details

Your Kobo is running an updated firmware/database version. As calibre does not know about this updated firmware, database editing is disabled, to prevent corruption. You can still send books to your Kobo with calibre, but deleting books and managing collections is disabled. If you are willing to experiment and know how to reset your Kobo to Factory defaults, you can override this check by right clicking the device icon in calibre and selecting "Configure this device" and then the "Attempt to support newer firmware" option. Doing so may require you to perform a Factory reset of your Kobo.

Discussion of any new Kobo firmware can be found in the Kobo forum at MobileRead. This is at https://www.mobileread.com/forums/forumdisplay.php?f=223.

Device database version: 174.
Device firmware version: 4.38.21908
