P: Catalog backup crashes and corrupt catalog even with the V 14.01

Issue(s):
- Impossible to backup => seems to corrupt the catalog at every attempt
- Catalog getting unstable + Very lenghty (over 30mn...) to repair *

(with the msg : updating catalog file format ! )

Environment :
Lightroom Classic Version Number: V14.01
OS Version Number: Windows 11 23H2
Computer: Intel i7-12700KF - 64Go - Nvidia RTX-3090 24Go

Steps to reproduce: backup catalog... (voluntarily or automated)

Expected result: more stability and the ability to backup safely
Actual result: losing confidence and fear to lose all my catalog
