P: Desktop: Crashing after trying to go to the Presets tab

That is probably related to the number of problems that Lightroom V10 is having on MacOS.

Many thanks for the quick feedback. Why does the software crash when I create a new preset or want to apply the development settings of one photo to another?

The solution is to get updated 64-bit presets from the vendor who supplied your presets. 

Hello everyone,

since my update to Lightroom Classic Version 10.0 the program crashes whenever I want to apply one of my presets, create a new one or copy the settings of an existing image to a new one. Since I deleted all presets (created and bought over years) I can easily edit, sort and export images. As soon as it comes to presets the program crashes. In addition my already finished pictures are displayed with a different look than before and load the preview including editing very slowly.

I use a MacBook Pro with 2.3 GHz 8-Core Intel Core i9, 16 GB DDR4 on macOS Catalina (version 10.15.7). I have already uninstalled and installed Lightroom. I also checked the catalog, cleared the cache, reset the preferences and used all tips I could find. 

After talking to some photographers I know, they reported similar problems. I hope you have a solution for the problem because I am using the software and presets every day and currently not able to work with them.

Best regards and thank you very much for the help.

Hello, so the problem is kinda back 😞 Today I worked in Lightroom on my phone and then I wanted to continue on the pc. I used some presets on my phone but when I opened it on the computer, I couldn't change anything in that picture. The picture was visibly modified but the PC lightroom showed that all the features are unchanged. 

Maybe reinstal of presets might help...?

Likey a bad install/corrupt preference file then. Thanks for letting me know!

It works again! Yay! Yipee! 

Thank you for your help and patience 🙂

Thanks.  I am going to recommend a two step process for you you. 

1. Clean Reinstall
2. Reset Preferences

Clean Lightroom Install Procedure

Close Lightroom

Restart the computer

Use the Adobe Creative Cloud App to uninstall Lightroom

Restart the computer

Install Lightroom via the Creative Cloud App without launching any other programs.

Restart the computer

Launch Lightroom

Wait 5 minutes

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.

Reset Procedure:

1. Close Lightroom.

2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom.

3. Overwrite the Preferences when prompted by the dialog.

4. Close Lightroom.

5. Restart Lightroom.

Does the behavior continue after resetting the preferences?

Ah sorry, this one is. 

I don't see Lightroom listed here. 

Is this an Activity Monitor shot taken during the 'crashed state'
