Hi Everyone…!
This may could help to solve this issue…!\
I have been trying to fix this problem since two days and I have tried every possible ways to overcome this error and Finally it worked for me on windows 10 X64. ( note: this problem is occurring on Windows7 and Windows 10 with latest Manger versions)
First step-----> Install Microsoft Edge Manually.
Second Step–> Install Microsoft WebView2 runtime Manually
You can get them on Microsoft Website, once you finish Installation restart your PC.
Then go to Settings> System>Apps&features. find Microsoft Edge and click on MODIFY once it’s done do same for Webview2 and Manager then restart your PC. Now try to run Manger and it should work without any problem.
Remark: if you install the the latest versions of Manager on Windows 11 it works smoothly no issues at all.
Thank you and hope this step fix your nightmares
