Lightroom Classic for Mac crashing on launch

[rhp1970]

I have not opened Lightroom Classic on my Mac recently--not since it was updated to v13.0.1--and today when I attemtped to open it, to export some JPEGs from RAW files, it crashed immediately.

I think this is the relevant info (with a unique folder name removed and replaced by <...>):

Termination Reason: Namespace DYLD, Code 1 Library missing
Library not loaded: @executable_path/../Frameworks/ahclient.framework/Versions/A/ahclient
Referenced from: <...> /Applications/Adobe Lightroom Classic/Adobe Lightroom Classic.app/Contents/MacOS/Adobe Lightroom Classic
Reason: tried: '/Applications/Adobe Lightroom Classic/Adobe Lightroom Classic.app/Contents/Frameworks/ahclient.framework/Versions/A/ahclient' (code signature invalid in <...> '/Applications/Adobe Lightroom Classic/Adobe Lightroom Classic.app/Contents/Frameworks/ahclient.framework/Versions/A/ahclient' (errno=1) sliceOffset=0x000A0000, codeBlobOffset=0x0008B200, codeBlobSize=0x00004220), '/System/Library/Frameworks/ahclient.framework/Versions/A/ahclient' (no such file, not in dyld cache)
(terminated at launch; ignore backtrace)

Should I uninstall and reinstall?

Rick, I followed your steps on my brand-new MacBook Pro and still acting the same way; once the splash screen shows for a second crashes  
The computer has the latest iOS 14.1
Advice?

I ended up using the "other versions" option to revert to 13.0 from 13.0.1 and now it works again.

Thanks for the suggestion, @Rikk Flohr: Photography , that is what made me think of this because it other versions is in the <...> menu in the Creative Cloud interface.

It is likely that it was the reinstall that cured it not the version you reinstalled. Given the known issue for people who downloaded 13.0.1 due to a server issue. Reinstall of 13.0.1 would likely work as well.

My symptoms were identical to the original poster's.  I reinstalled 13.0.1 and the problem was indeed fixed.  Thank you.

I have the same problem. LrC wouldn't start after update. I'm on the latest macOS, freshly restarted.

I'd argue this is not a slution, but a workaround.

Thankfully it didn't happen while I have urgent client work...

Update on my issue 

It seems like my user was corrupted

I created a new user copied the files I needed to an external HD and transferred them to the new user  problem solved

Although the computer was brand new, I migrated from an old one and the problems migrated with it.

Dropbox was also part of the problem when it backed up the computer some time ago
