And one of the foundational (but non-obvious) assumptions of materialism is that nothing is truly random.
In that case I am not a materialist. I don’t believe in any entities that materialists don’t believe in, but I do believe that you have to resort to Many Worlds in order to be right and believe in determinism. Questions that amount to asking “which Everett branch are we in” can have nondeterministic answers.
No worries—you can still be a materialist. Many worlds is the materialist solution to the problem of random collapse. (But I think that’s what you just wrote—sorry if I misunderstood something.)
Suppose that a particle has a perfectly undetermined choice to go left or go right. If the particle goes left, a materialist must hold in principle that there is a mechanism that determined the direction, but then they can’t say the direction was undetermined.
Many worlds says that both directions were chosen, and you happen to find yourself in the one where the particle went left. So there is no problem with something outside the system swooping down and making an arbitrary decision.

Those sorts of question can arise in non-QM contexts too.
