Description
I am getting errors with the latest version of Edge (143). I have tried both automatically and manually to download the correct Driver Version... Unfortunately without luck... I am checking the version in Drivers and it is version 143...

Research direction
Start at DWLibary/EdgeUniversal.cs line 117, where the DevTools session fails, then trace the callers in DualWriteHelper/AppExecution.cs at lines 179 and 89. Check how the current Selenium Edge DevTools support handles Edge 143 and verify the application can retrieve its token without the unsupported-version error.
