Device Crash with setFrequencyMod on ring modulator

Creating an LFO to modulate a ringmod as follows works in the emulator (2.7.6, Mac), but crashes with e0 on the device. Here’s a main.lua that works in the emulator but crashes on device:

local snd <const> = playdate.sound

local synth = snd.synth.new(snd.kWavePODigital)

local channel = snd.channel.new()
channel:addSource(synth)


local ringmod = snd.ringmod.new()
ringmod:setFrequency(987.77)
ringmod:setMix(0)

local freqmod = snd.lfo.new(snd.kLFOSine)
ringmod:setFrequencyMod(freqmod)

channel:addEffect(ringmod)

synth:playNote(440)

function playdate.update()
    print('bye')
end

Specifically it is this addition which causes the crash:

local freqmod = snd.lfo.new(snd.kLFOSine)
ringmod:setFrequencyMod(freqmod)
