I have switched to Windows 11 and I have had some loading issues the last couple of days as well.
On the other hand, I've had a history (years of it) of timing out really fast on this board but have remained logging in since I updated.
In general, I've found with the proliferation of bloated AI stuff, everything has been hanging/processing a lot. I disable AI options every single time I can... but they keep being added in as the new thing needed or not. I don't need or want "them" going through my email summarizing someone's brief thought to me.
