Intermittent concurrent map writes error during update preview

[stelmod]

What happened?

Intermittent failures when updating a stack. This is happening on two different pulumi projects and different stacks within each.

Steps to reproduce

Hard to tell how to reproduce, given that it only happens sometimes for us. The command we run is pulumi update --yes

Expected Behavior

Successful stack update

Actual Behavior

Failure with one of these errors:

• concurrent map read and map write (trace)
• concurrent map writes (trace)

Output of pulumi about

No response

Additional context

This is happening both when running pulumi on a dev laptop as well as CircleCI, all running the latest versions of pulumi.

Hi there @stelmod thank you for reporting this issue! Looking at the stack trace, it looks like this is the same issue we fixed today in #11151 and we will rollout a patch version as soon as possible. I will be closing this as duplicate of #11153
