I've been bumping into the same problem with a Copilot I created back in November/December. It was working great with Sharepoint/Generative Answers for a while. Then recently it stopped providing answers through the generative answers topic (just responds with blank).
I get this error occasionally when trying to disable/enable generative boosting.
HTTP Status:PreconditionFailed, ServiceRequestId: ab00ceab-436c-485b-9a84-c2a6079735ab [0x80060882:ConcurrencyVersionMismatch] The version of the existing record doesn't match the RowVersion property provided.
I get this error when saving any topic at all while Conversational Boosting topic's status is set to On.
Object reference not set to an instance of an object.

I feel that these errors are related to my Copilot's inability to generate answers anymore but I'm unable to pinpoint what's causing this. I've tried creating a new bot and copying the code for the gen boosting topic with no luck. Tried disabling/enabling but I'm unable to due to the errors.
One thing I've noticed is that the conversational boosting is constantly marked as being edited by me, even for days at a time. I noticed the problems start to occur more frequently as I switched to the web-based copilot studio as well.
Any help in diagnosing this would be highly appreciated! My Copilot went from being extremely useful to being a brick.
