Light Room classic CC catalog conversion crashes - can no longer use Lightroom which is part of my bread and butter apps - is there a work around - can you go back to the old version and how can you stop having to upgrade untested programs

Hi, please submit the crash report. Also, it would be great if you can share us your catalog(only lrcat file), it would be easy for us in reproducing the issue. I have sent you a mail regarding the same.

Hi, the same issue here. After LR update do LR CL it needs catalog migrated. But the migration is not successful (ends with a dialog below). No visible crash report, an important work stucked. How to downgrade to previous version or how to successfuly migrate the catalog to the new version?

same here, went back to previous version using the Adobe CC Updater application, next to the LR CC name, there is a dropdown that contains "other versions", clicking on that will bring you to the previous version.

Same here. Crash every time I try to upgrade my catalog. The Lightroom Classic CC installer also helpfully uninstalls my previous version so now I am completely blown out of the water and can't work - not clever Adobe. I've raised a crash report to both Adobe and Apple (running MacOS 10.13) but am very keen to know how I can downgrade to my previous, working Lightroom CC so that I can continue providing service to my clients.

Edit: For the benefit of others reading this, I've just discovered that the Creative Cloud app allows me to install old versions of Lightroom so I'm currently re-installing Lightroom CC in the hope that this will get me back up and running pending a working version of Lightroom Classic CC.

Edit 2: After reinstalling the downlevel Lightroom CC, it is also now crashing whenever I try to start it up. I am not happy.

It seems I've resolved my problem this morning. After uninstalling LR, rebooting my Mac and reinstalling, I can now open LR Classic CC without it crashing and it's able to read the converted catalog. I've not actually used it yet so can't comment on stability but at least I see my pictures again.

I've just tried this but it hasn't fixed the issue for me.

I was premature in my last comment. After a reboot/reinstall, the application opened successfully once but then started SEGFAULTing again on every attempt to start it. Based on a hint I found elsewhere, however, I disconnected my 2 card readers and now it's working reliably! It seems that having both my Lexar USB3 XQD reader and  LexarUSB3 SD/CF reader  attached was enough to make LR crash every time. Hopefully this should be fairly straightforward to debug. I've sent another crash report  to Adobe with this information appended.

This issue has happened to me.  I'm using Windows 7 Home Premium and whenever I try to upgrade my catalog it causes the whole operating system to crash and the computer restart.  Uninstalling and reinstalling has no effect.  Lightroom now completely unusable.

Disconnecting Card reader solved my problem. After that, I reconnect my card reader and then it work.

In case anyone missed this in my comment earlier, the solution to my problem was to ensure that I disconnect my card readers prior to running Lightroom. The problem persists whenever I have both USB3 XQD and SD/CF readers attached but the application runs reliably without them. I have yet to determine whether it is stable with one reader attached but, even if it isn't, I can use PhotoMechanic for import and image culling then switch to LR for edits after removing the readers.
