Help needed to restore deleted Lightroom folders and sub folders and to open my backup catalog

I accidentally deleted some  lightroom folders and sub folders with around 2000 images  that were not showing their files when I opened them. The original raw and edited files are safe on my harddrives, so its just lightroom they've been deleted, along with all the editing processes I presume that I would love to restore.

I understand thanks to user  Johan Elzenga reply below I can just close the program then open a back up catalogue, lightroom doesnt find my back up catalogs when I direct it to them. see attached photos. So I need help connecting my back up catalogs to LR classic so they recognise them again

photo 1 shows the location of the catalog back up

photo 2 showing its properties to check its the right file

photo 3 shows lightrooms response when trying to open the catalog

 Im not backing up or working on anything in LR classic until I have resolved this issue.

Many thanks in advance!
