(2.8/9XX) Addons show up in the list but not in the interface! I read lot of questions on forums and all, but mine is slightly different.
Sometimes I click install, choose the addon etc. Most of the time it appears in the list, but sometimes I only get a notification in the status bar &quot;module installed...&quot;
Now my real problem is that while it is installed in the preferences, it doesnt show up anywhere!
Just cant use it!
It was happening in 2.8x and still does in 2.9x (I tried the beta and 2.92 alpha as well)
I did not mind so much but I really need some of those now...
Which ones I tried?

Sverchok
2 addons for more sculpting brushes
animation nodes...

Any idea for me? :)
EDIT: I also tried while running blender as administrator (I am on windows 10)
Thx

one of areas on screen you have to change to type Sverchok
