Lightroom Classic startet nur noch als Hintergrundprozess

[Sven29649271pa7z]

Hallo,

Ich habe seit kurzem das Problem, dass Lightroom Classic nur noch als Hintergrundprozess ohne Fenster startet. Habe Lightroom Classic schon komplett deinstalliert und neu installiert, was aber das Problem nicht gelöst hat.

Ich nutze Lightroom Classic unter Windows 11 mit einem AMD Ryzen 5600X und 32 GB RAM. Graphikkarte ist eine NVIDIA GeForce GTX 1650 mit 4 GB Arbeitsspeicher.

Hatte jemand schonmal das gleiche Problem oder kann mir weiterhelfen? Danke!

In a first step try resetting the preferences of Lightroom Classic:  https://helpx.adobe.com/lightroom-classic/help/setting-preferences-lightroom.html

Backup your preferences prior to resetting the preferences:

If this doesn't help try the following steps:

• Close LrC if open (if the UI isn't visible shut down LR via Taskmanager)
• Locate the file named "metrics.json"
  File Locations: 
  Mac: /Users/<username>/Library/Caches/Adobe/Lightroom/metrics.json
  Win: C:\Users\<username>\AppData\Local\Adobe\Lightroom\Caches\metrics.json 
• Remove or rename the file

Check if Lightroom starts normally.

Please remeber: The folder AppData is normally hidden, so make sure that hidden items view is enabled in the Windows Explorer.

If this also doesn't help, we need more informations about your system.

Which operating system do you use?

Which version of Lightroom do you use?

Please post the exact version and not only phrases as "recent", "latest" and so on.

I have the same issue. I resetted the preferences and tried to delete the json file but this file isnt present in my folder. I downgraded the installation and updated it again, but still no change. I also updated the drivers etc.

I am using Windows 10.

I need help please

Suggestions-

1) Try opening a new Catalog (Start LrC with holding down [CTRL] key to access the [new catalog] button).

I have seen a report that a corrupt catalog placed LrC in a 'never-opening' situation.

2) Many moons ago (for Lightroom 5?) setting the Catalog with 'High Priority' corrected the problem of the app running as a background process. Worth a try!

Or see my notes on setting High Priority for a Catalog in attached doc.-
