Lightroom crashes on book module

[G244116311xnh]

Hello,

im using lightroom classic 12.1 on a mac studio ventura 13.1.

Lightroom crashes in all my catalogs when try to work on the book module.

Everything seems to work just fine exept the book module. when clicking on the book module, lightroom crashes immediately. 

Do you have any ideas what might causing this problem?

Till yesterday i was able to work with no problems.

Thank you in advance

When LrC behaves strangely, then it's always worth checking whether refreshing the preference files helps. Follow the intructions in Method 1 at https://helpx.adobe.com/lightroom-classic/help/setting-preferences-lightroom.html
