After updating to Lightroom classic 13.5 starts/loads very slow.

After updating to Lightroom Classic 13.5 it starts/loads really slow.  Once started it seems to work as norma

Mine appears to be a bit quicker.

• When you start LrC, and you see it bring up that Spach Screen, does it apparently hang up while Reading the preference file? Or does the Splash Screen come and go, and LrC slows down a bit just after that?

Once started it seems to work as norma

• You are not having any odd behavior somewhere in LrC?  Something that may indicate a preferences file issue.

It is not the splash screen but after that screen when it tries to load the Library page, i.e. the panels.  I have 3 default panels in the Library Module.  The left navigator panel, the center photo files, and the right is the drill down on the Library module.

Oh.... and one more thing.  It is happening on both LR classic and LR.  I have a feeling that there isa something going on with my Windows Explorer.  However, everthing else works fine so I'm not sure.

Possible diagnostic

• In LrC, in the Library Module, select an image
• Check the Histogram, make sure this is an Original Image (i.e. not missing)
• If the image is missing, try another one
• Enter the Develop Module
• Close LrC
• Reopen LrC
• Was that faster?
• And did it start in the Develop Module with that image?

If LrC brought you to the image in the Develop Module quicker that the previous opening into the Library, perhaps something is wrong in the catalog. Thinking missing photos, missing folders

If LrC did not upon restart bring you directly to the Develop Module, and to that image, perhaps something wrong with preferences file??

I found the problem.  It was/is my catalog.  I am not sure what happened but when I move the previous version catalog and photos to my laptop with the latest version LRC it works fine.  If I do the same test with the latest verion of my catalog, it fails.  I can go back to the previous version and again it works.  The issue I now have to solve and I'm working in it is there a large number of photos that I had added between the 2 catalog versions.  So I am going through teh exercise of adding the new photos to my laptop LRC. 

Thank you for your help.  Your last mention of maybe it is the catalog got me thinking I should try the old version on my laptop.  Thanks again for your help!!
