Never had an issue here. I use AO plugins on big projects all the time. running Reaper on M1 Mac, usually in AU form.

I use Reaper as well. Which one is crashing? I’ve never had any issues.

I’d love to see that. So far though, Analog Obsession doesn’t seem to make the kind of complex plugin interfaces that a dynamic eq would need.

I’d be curious to know whether it’s the eq curves, the compressor behaviour, or (the lack of) saturation that makes TDR Nova not as musical as AO plugins? I’m not disagreeing at all, just looking to learn more.

they are far from stable. the only eq i use from them keeps crushing my reaper from time to time. very annoying. don’t spread lies

Okay, results are: The curves are different but in a good way. UREQ has smoother curves, even with UREI’s bandwidth set to maximum. UREQ’s overtones look authentically analog-ish.
There is something special about the curves, though: Cutting is kept narrower than boosting which is very useful if you want to cut resonances or boomy frequencies.
I gotta say, I’m very pleased with its sound.
If you want a quick and easy mix EQ you might like this one.

When have you checked the last time? Seriously, I can’t even remember the year when Analog Obsession was unstable. Reviewers all over the globe praise AO for his plugins so take that as a gentle hint. 😉
