I upgraded from my current subscription LR to the new Lightroom Classic version (not LR CC) and now it crashes every time I start it up. Suggestions? I went back to the 2015 version and updated that so I could still edit as my older version had somehow lost the synch double arrows.

Greetings Frank,

Lightroom 7.0 or later is now required to sync files with the Creative Cloud. 

Reverting to CC2015.x will cause a loss of sync capabilities.  My best suggestion is to see if we can isolate the cause of your crashing when your have the Lightroom Classic CC version running. 

Did you uninstall Lightroom Classic CC or is it still on your system?

I was using the most recent LR creative cloud prior to the split between the new cloud version and the old one. I did not uninstall but upgraded to the update version of classic or so I thought. It had the same icon. When the new version crashed I saw another version of the old program with the old icon and updated that and no I have access to my photos and synching but can't seem to synch separate collections. I have no desire to use the new cloud version because I have over 2T of photos.  Just want to be able to use LR mobile to edit photos.

My recommendation Frank is to use the Adobe Creative Cloud App to uninstall Lightroom Classic CC. Restart your computer. Then use the Adobe Creative Cloud App to reinstall LIghtroom Classic CC.  This is Lightroom 7 the next version of  6/CC2015.x and not the cloud version  you are attempting to avoid. 

After the Uninstall/Restart/Reinstall, does the crashing still occur?

[Solved] or at least it worked for me...

 

I had similar problems twice recently with Lightroom. The first time was shortly after the upgrade to version 8.0, September? October 2018?  The symptoms were simple: start Lightroom, and within 60 seconds, crash report dialog.

 

I tried various ways to fix this, the details of which I forget, but in the end, I got out of the problem by doing a Windows system restore. I was fortunate enough to have a restore point that was just a few days old. After that all was fine.

 

The second time I had this problem was last night. Suddenly Lightroom was very slow to load and then started crashing again. So I took a different approach.

 

My suspicion was that there was something wrong with the catalogue itself. I therefore deleted the catalogue file (SomeName.rlcat), and the two files that Lightroom creates named after the catalogue file:

                SomeName.rlcat.lock

                SomeName.rlcat-wal

And the folders

                SomeName Helper.lrdata

                SomeName Previews.lrdata

Then I restored the catalogue file SomeName.rlcat from my last backup and restarted Lightroom. That solved the problem, at the cost of throwing away the image previews.

 

Thankfully I have Lightroom set up to do a catalogue backup every day.

 

Hope this helps someone else.
