Lightroom Classic 10.3 crashes on startup

[alibphotographyy]

Hello! 

I just downloaded Lightroom Classic today and I haven't had any other issues with any of the adobe apps on my desktop. Everytime I go to open the app, it immediatley crashes. I have tried renaming the SLStore and SLCache folders to SLStoreold and SLCacheold and that hasn't worked either. I recently backed my entire mac onto an external hardrive, however I put the System Library file back onto my mac. Any suggestions or solutions?

Hi Albi

I'm trying to parse your statement "I recently backed my entire mac onto an external hardrive, however I put the System Library file back onto my mac. Any suggestions or solutions?"

I need to understand: are you trying to run your Mac from an external drive? Please verify.

If so, that will not work, at least as far as allowing it to run like a Mac normally would and I think that might have something to do with this. 

And if you are trying to run your Mac off an external drive, why are you doing that? Are you running out of space on your current internal hard drive?

(and if I'm reading this wrong I apologise.)

No I’m not trying to run it from an external hard drive!

OK, thanks for verifying that part. 

But I'm still confused as to why you replace the System Library Folder back onto your computer? Did you have any specific reason for this? Did you by any chance keep a copy of the original incase something went wrong?

How did you install LrC?

Be specific, be wordy. Details..

Is this a brand new installation of LrC?

Or is it an upgrade?

Do you have previous LrC catalogs?

Quote, you stated "Everytime I go to open the app, it immediately crashes."

Please clarify does Lightroom Classic boot and open the Catalog and then suddenly crash or does it just fail to launch the Catalog?

If you were installing LrC to upgrade an earlier version please provide details of your upgrade procedure and experience.
