.net 9 Blazor Server application pool recycle issue

Since we've upgraded to .net 9 (coming from .net 8) we experience that some of our customers can't click on any buttons/links/.. being rendered in Blazor Server. The click events are not being accepted/processed.

Server 2019, Blazor Server, .net 9.0 in-process published, IIS.

We've seen that when we see an Event id 5074 WAS in that the application pool recycles that some users in production are affected by the "ignoring of click events". These are not always the same users.
These users are not being able to work in the applicaton as the click events are totally ignored.

We've never seen this in earlier versions of .net but since .net 9 we experience this sometimes in production.

Anyone experienced the same? Suggestions?

When a customer calls with the issue, the CPU (7%, 6%) and Memory (70%) are normal...
