Since using Pre-Release 2.3.1 on Windows, I find that ALOT of times I cannot complete updates to themes and plugins as I get this message. In most cases, if I wait long enough before attempting to reload the wp-admin (or if I stop/start site again), I will be able to get in and realize that the updates were completed, just not gracefully.
I always leave that switch ON
Got it. This is something we’re actively looking into.
In the meantime, the next time you update several plugins/themes at the same time go ahead and try disabling Faster Docker Volumes temporarily.
