All After Effects versions crash after installing AE 2023 on MAC

Hello

I’ve been using 3 versions of After Effects - 2020, 2021 and 2022.
Yesterday I decided to update 2022 to 2023. It was successfully installed from creative cloud but on launch I was told that it is not compatible with my current OS.
So I have installed 2022 back.
After that non of my After effects version are launching. I get the same crash report every time.
I’ve uninstalled 2022 and 2021 and tried to reinstall 2022 many times. Unfortunately I don’t see an option in CC of installing older versions anymore.

I was not planning to update my system as I use some old plug-ins that run only on older versions.
What has happened and hot to solve this issue? It completely paralysed my work.

My current versions are:

After Effects 17.1
After Effects 22.6.4.

MacBook Pro 16 - 2019.
MacOS Catalina 10.15.1
