[2022] When are they patching this horrible Anno 1800 memory leak?

I'm crashing every ~1.5-2 hours of gameplay with an error that says: "ERROR - Out of Memory", text: "Oh noes :( The Application tried to allocate 2MB, but there is not enough free RAM left"

I have 32GB of RAM and an RTX 3070ti. I have all the latest drivers, and I play lots of highly demanding games, but Anno 1800 is the one game that gives me problems. The crashes are absurd. None of the latest Total War or ArmA games do this, and I play those with multiple Chrome tabs + extensions running, + Spotify, + Discord. It's pretty ridiculous that people suggest this isn't an Anno 1800-specific memory leak, and it's crazy to see how many people are having this problem when you google it.

I've monitored processes in the background and closed EVERYTHING but Anno + Steam + Ubi. Nothing uses very much RAM, but after ~1 or 1.5 hours of play, Anno starts using 90% of my RAM, with the rest of my system processes (Steam, etc) using another TOTAL 5%. That means when Anno eventually spikes to 95%, that puts me at 100% and my game + Steam + Ubi Connect all crash.

I see posts all over the web about this dating back >1 year, and the responses are useless. "Buy more RAM." "It's probably Chrome/Firefox hogging your RAM." "Re-seat your RAM." etc. None of those are helpful.

I also saw someone mention using Razer/other 3rd party software to either limit Anno's RAM access/usage, or boost RAM performance (lol) and of course none of those seem to work, according to the comments.

This is getting to the point where I practically don't want to play this anymore.
