Dear all Master of Unity CODERS:

I'm a new game developer from China, I have to said I like unity very much, unity make things much easiler and more effective. And I paid for the plus license(Cost me a lot T_T)

But now I meet some huge problem during the month. Please help!!

### 1. can't open unity project.Edior Version:Both 2019.3.15 or 2019.4.0
First I can not open my project in my PC-A( call it computer A) ,but it works well in my laptopB(computer B). When I try to open a blank project it just flash the unity editor logo and back to unity hub's project list. Editor can be opened by create a new project (2019.3 or 2019.4) ,but I can not open the project again after first time open. And I found I can not Switch platform to Androdi ,it shows "Your License does not cover Android Publishing"

And I hate chinese version of unity ,just feel strange, and i try to use oversea IP, but still get Chinese version (same issue) installed by hub.

List what I tried:

-Turn off the firewall
-Install the unity by hub (always get Chinese version ,I hate that)(something like 2019.4/china_unity/release)
-Install the unity by download form https://unity3d.com/unity/qa/lts-releases , and get UnitySetup-Android-Support-for-Editor-2019.4.0f1.exe installed - not working ,some issue -Try to use reinstall hub or higher version of hub, which is 2.3.3 not working
-Try to use some proxy to run unity ,not working
* -Try to fix "ERROR Failed to connect to local IPC" - I DON'T KNOW HOW TO DO

### 2. Problem - the unity asset store is really slow]
HTTP_proxy environment verable is looks like not working very well - especially china version's editor. Is their any other way can use proxy in unity editor?
