I'm having the following assertion failure on Pulumi update:
```panic: fatal: An assertion has failed: 'Check' and 'Diff' must be called before 'Update' (urn:pulumi:jamesm::xxx::pulumi:providers:pulumi-python::default)```
This appears to be on my default Python provider in my pulumi-aws stack. Any suggestions on how to diagnose why this is happening? I have other stacks deployed form the same project that aren't encountering this, so it's a state-related issue with this stack.

It looks like it is related to 20529. I see that issue is already labeled a p1 and is assigned so the team is working on it.

Were you able to work around the issue for now?

Yeah, if I reduce the parallelism to 1 task at a time, it will complete. I've commented thus on the bug.
