@Etonkovidova -- is this the sort of error that should be addressed soon? What are users experiencing?

It means that for some users, checking the box to enable Flow for their user talk page fails. The error happens silently, so the user sees in their preferences the box checked for enabling Structured Discussions on their talk page, but when they view their talk page, it's still in its old wikitext format.

I have proposed T248309: StructuredDiscussions (Flow): Prevent users from enabling Flow on their user talk page (beta feature), I think unless we are going to allocate time to sort out bugs like this (as well as fixing the root cause of T70526: Flow: InvalidDataException "Flow workflow is for different page" from WorkflowLoaderFactory.php) we should probably not allow users to enable a feature with unattended bugs.

Per T234241#6334929 this seems like the opposite, users cannot *dis*able Flow on their talk page. (No guarantee it's the same bug, but the stack trace is the same.)
