Adobe Lightroom Classic Version 10.1 and macOS Mojave V. 10.14.6

Adobe Lightroom Classic Version 10.1 does not work correctly on macOS Mojave V. 10.14.6.

I'm a Creative Cloud subscriber photographer and  no I can't edit my work in good time.

How can I reinstall a version that works properly?

I've  been working with Lightroom since Version 1, and if there's no solution, I'll have to abandon this application.

My MacPro is a mid-2010 machine (with 32 GB of Ram), so I can't install macOS Catalina or macOS Big Sur.

Thank you
