Bug Unity Hub hangs on "In progress" install (3.5.0)

Installed fresh UnityHub (3.5.0), got fresh credentials, Hub offered me 1 Unity version (2022.3.5f1) to choose from to install. So i clicked it .. Unity downloaded and installed in 5mins, and 2 items are still pending for an hour in the queue (docs and webgl build support). Firewall is set to give Hub complete freedom. Id give more feedback if i knew it would be beneficial and if i knew how (the Hub itself doesn't exactly give much information on the issue).

 

After clicking the Close [X] button on the 'active download', Hub deletes the whole Unity Editor installation it just completed (shouldn't delete it, if only docs failed to download - methinks). After next clicking Installs (under Projects, in Hub), Hub tells me i've got the Editor installed, which is not the case. When i click the COG icon and then 'Remove from Hub', nothing happens. Saving grace? Unity Archive.

 

I've managed to manually install the (same as above) Editor and link into Hub using Installs / Locate. Then in Projects / New Project, after selecting a 2D Mobile template, creating project (there is another error with elevated permissions, which i fix and then) after the empty project launches, i instantly get following error in Editor: This is on LTS, template provided by unity, empty project.
