Fatal error: Cannot access protected property Drupal\Core\Session\UserSession::$uid in admin_menu.module on line 232

Gave it a go with and without the patch at simplytest.me. With the patch applied I got this lengthy error:

Warning: Invalid argument supplied for foreach() in _drupal_schema_initialize() (line 313 of core/includes/schema.inc).

After hitting the back button, I got this one:

I tried testing this over @ simplytest.me, but I got this error:

If you have just changed code (for example deployed a new module or moved an existing one) read http://drupal.org/documentation/rebuild

Additional uncaught exception thrown while handling exception.

...this might be related: #1422876: Exception: theme() may not be called until all modules are loaded. in theme()

It appears to enable despite the fatal error, and you can test the above patch.

Well I gave the new patch in #11 above and I did get the same error as in #8. I then tried switching to /admin to see if things work as you say, but all I got was a huge "The website has encountered an error. Please try again later." page with this:

...upon refreshing the same page, the error changed to this (only the last portion of the above error):

I also tried a combination of the patch in #11 together with #1965552-21: Convert service registration to YAML, but that fails to apply over @ simplytest.me.

I'll give it another go if someone provides instructions of the patches required to make it work.

Filed #2181387: 8.x modules not downloaded/installed when selected as an additional project. for the issues I've been having over at simplytest.me with admin_menu 8.x. Until that issue is resolved, I cannot find a way to apply multiple patches to admin_menu 8.x. Perhaps I'll setup a local environment and test but my time is limited currently (more than it already was) so I can't promise anything.
