Unity broken since hub update to 2.4.1

Unity Engine
,
1

hello,

my hub updated to 2.4.1.
since then I experience multiple issues:

when hub starts up, it complains that “unity” is already in the list, which it is not.

when I open my project, it opens 2 windows instead of 1, the 2nd window being completely grey. If i click in that window, unity hangs and I have to terminate the process.

if it does load, it complains about issues loading the window layout, offering me to load defaults, reset to factory or quit.

none of the options solve the issue.

I tried checking for an update of the editor, but nothing happens once I click “check for update”.

There are no compile errors in my code.

I cannot use unity any more.

Can anyone please help me solve this?
I am completely lost…

Thanks!

I tried installing the new unity version. It upgraded, but the issue remains.
How can I access my project again?

I restored my project from a backup. installing the new unity version using the web download installer fixed the hub. restoring my game form backup fixed at least the biggest issue, although it still complains in the console, but at least it loads.

— solved —

What’s the console message say?

Here’s a thread on the layout issue, though you say you already resolved that one fortunately.
