Updated Lightroom to 11.0 this morning. The first message I get is "Cannot convert catalog" and reference to an Adobe webpage.
I've checked and there is no LRCAT.LOCK file. All my other catalogs have converted with no problems. It's the big one (of course) that is an issue.
I'm running an Intel iMac 27in (2019) with 64GB Ram and about 300GB free on the main hard drive. Photos are stored both on the main drive and an external drive. This is a configuration I've used extensively for a few years now and have about 112000 photos in the catalog. The OS is macOS Big Sur v11.6.
Any suggestions are appreciated. In the interim I've started a new catalog and am "adding in place" the photo files. That means I'll lose the collections, but I guess there are worse outcomes possible.
Lightroom Classic 11.0.1 was released on 11.15.2021 and contains a fix for this issue. Please refresh your Creative Cloud Application ([Cmd/Ctrl]+[Opt/Alt]+[ R ])and install the Lightroom Classic update. Thank you for your patience.
