Sorry I was out yesterday.

I think it is interesting to read this started the day after changing to cloudflare DNS. I goggled timeouts and Cloudflare, plenty of recents hits.

Have you tried uninstalling your adapter and allowing windows to re-install?

I would then do a Network reset although the mini tool box does most if not more.

and final I would do an in place repair.

Repair Install Windows 10 with an In-place Upgrade

I know it is after the fact but I would also look into and start using a product like Macrium Reflect. Then you just quickly restore to an earlier time. Saves a lot of grief.

So uninstall adapter, reinstall, network reset and finally an in place repair.
