Blender takes 20 minutes to start

Hello. I hope you can help me with this, because my patience with blender is totally out. When I start blender, it will open a ‘command window’, with blinking white “underscore”? Blender took 1 minute or less to start, but for some reason, now it takes exactly 20 minutes (well, 19 minutes and 3/4, used stopwatch). What could be the reason?

Thanks for replies, Nico.

not much to go on from that post, the first obvious quesion is; what changed between the 1min boot [still very long in my opinion, mine fires up in seconds] and the 30 min one? have you had any updates that might have failed/impacted, added any new AddOns to Blender etc? there might be something in your event logs, if you’re using Windows. is anything else having the same issues? if not a simple uninstall/reinstall might sort it.
