Microsoft Edge opening with Blank White Screen

Problem:

We are unable to use the Edge browser version 115, 116, 117 and we are getting white screen. However, it was working on 114 version.

Scenario:

When we are using the direct Windows server 2016 it's working fine. The issue is only when we access it through Beyond Trust Jump item we are getting the white screen in Edge browser version 115, 116 and 117. However, all other browsers are working fine.

Environment:

Operating System: Windows server 2016
Browser Version: 117.0.2045.60

Cause:

We found that the Citrix API is hooking onto the Microsoft Edge process.

Resolution:

By adding the below registry which fixed the problem.

Key: HKLM\SYSTEM\CurrentControlSet\services\CtxUvi 

Value Name: UviProcessExcludes 

Type: REG_SZ 

Value: badapp1.exe;badlongname.exe;badapp2.exe;msedge.exe 

Note : Reboot the server after the Registry change or the fix will not work.

I have cleared all resource-consuming locations ( WinSxS , TEMP directories, user profiles, outdated updates , etc.), but it didn’t have any evident effect. At last, I have found that a large part of a system disk has been occupied by System Volume Information folder. Let’s consider why we need System Volume Information folder in Windows systems, what is stored in it and how to clean up it. Note .
