Sounds pretty easy to make. I would go for a saw wave keys kind of patch, with a long decay on the amp. Keep the filter quite close for a darker sound and tune by ear. Like the other person suggest you need a warm chorus, the TAL is perfect for that. Add a good amount of reverb but use mostly the decay of the sound to make it sound like in a space. It sounds like there is a tape-like effect / lofi effect with wow and flutter and pitch mod. There's many plugins that can add this effect, look for lo-fi plugins, you can add it at the end of the chain (after chorus and reverb)

I tried first using basic low-pass filtered saw, but couldn't get the similar character. It was somewhat ok, but there was something missing. The original sound has a nice lush or haunting character. It sounds like there is also some band-passed saw oscillator layer, and it's a bit out-of-tune compared to the main saw osc. I tried also various filter types with a single saw osc and could not get close to that character. Adding an out-of-tune bandpassed saw was quite significant improvement. Also adding some FM from noise to that second osc makes it a bit lusher. The bandpass effect can done by removing lowest harmonics of the second saw osc in wavetable editor (if there is only one polyphonic filter, like in Serum). That's what I did in the preset posted above.
