I wonder if anyone has experienced the same problem. Whenever I try to import IE favorites in edge, the program crashes. Looking at the favorites that were imported successfully, I realized that edge crashed the moment it encountered a link that contained a ftp:// prefix instead of the usual http or https. This has been happening with every build of Windows 10 since the feature of importing IE favorites has been implemented. If I temporarily remove all the links using the ftp protocol from my favorites and launch importing again, the operation completes successfully.
