Newer versions After Effects has to reduce their pride

I was using AE22 before my laptop got damaged. I don't have the money to fix or get a new one so I am currently using a very old laptop with weak specs and can only run Adobe CS6. Such a downgrade, right?

But the problem is most of my old files were in 2022 version, Most files from Envato Elements is also from 2019 upwards. So it's really a chore doing projects from scratch all over again. Would be nice to be able to open newer versions AEP on older versions.
