would suggest you to follow the below steps :
1. Go to Lightroom Preferences> General tab
2. Disable the option "Show App Photos Screen"
3. Relaunch Lightroom
then, try to export a batch again.
везде пишите это, но это НЕ РАБОТАЕТ!
it is a way doesn't work
Lightroom still freezes when I try to export a batch of files as jpegs. I tried uninstalling and reinstalling Lightroom and the problem continues.
CC 2015.2.1 has solved some of the reported export problems but apparently not all. Please add details of your issue to this topic in the official Adobe feedback forum: Lightroom Release 2015.2 Crashes Upon Exporting/External Editing. Include the version of LR from Help > System Info (not "the latest release"), your version of Windows or Mac, and details about the export, including the exact export settings.
Hi. The problem began after updating on October 6.
Having launched the program without any actions in a background of system or in Lightroom in five minutes of CPU boots to 30%.
Lags simple actions like a crop, etc. of Export of a photo hang up it doesn't influence.
It was the day before yesterday rolled away perfectly works at Lightroom 2015.1.1 and all! But yesterday there was "fixed" 2015.2.1 updating and I thought problems solved. But all the same hangs up in inactivity.
Win 10 x64, GTX 660, i5 3470 - GPU uncheked
there is no other way out
with 1.1 I won't be updated more
Since i'm on Windows 10 Lightroom is unstable.
The previous version was lagging during importation of new pictures and sometimes in developpement mode. And now with the last update it's allaways having slowdowns and lags. I really cant work at all. I'm on a powerfull workstation so it cannot be a lack of hardware ressource.
Hope it will be resolved soon, but I think I need to go back to an anterior version to work.
"The last update" is ambiguous because the Adobe updater fools people into thinking they're on the "latest" when they're not. Do Help > System Info to see what version you're actually on. If it's CC 2015.2 / 6.2 or CC 2015.2.1 / 6.2.1, then Adobe Chief Customer Advocate Jeffrey Tranberry recommends rolling back to 2015.1.1 / 6.1.1 until Adobe comes out with a new release: http://www.lightroomqueen.com/how-do-i-roll-back-to-lightroom-2015-1-1-or-lightroom-6-1-1/
