What I wanted to say is that Android handles RAM by itself and there is not much you can do about that. This also means that 100 MB free on start up is not necessarily a bad thing.
I see however that being only able to have one app active is annoying and might be a problem.

I am not an Android developer so I don't want to give you false hopes, but we would need much more information to help you. Asking for the option to free RAM might hint that we are dealing with an xy problem.

So, what device are you running, which version of LineageOS, what apps are you running? Have you already tried to disable the apps battery optimization etc.

Ok so now my phone is showing 50% ram usage and apps are working fine without crashing.

For content, I'm on Lineage 21 and my phone has 3gb of ram. This is fairly perplexing and it did not happen on Lineage OS 20

Moto g7 power

It seems to fine as of now. I'll keep my eye on it as this smells like a memory leak
