Same or similar problem

edit 3: I completed all steps outlined in the various DCS wiki pages for troubleshooting. No joy. Performed a windows 10 reset (lose settings, keep files) and after installing the latest MS Visual C run-times, DCS works 100%.
edit 2: Opened a ticket #81702. I will update here if I get some help.
edit: uninstalled Bit Defender, deleted temp folder, ran repair and update. No joy.
I'm have the same or similar problems. I did a clean install of DCS.openbeta with no problems. Upon initial launch, it flashes the update window and the progress bar scans left to right and then the window closes. The login screen never appears, but the DCS.exe process is visible in task manager. Any further launching from desktop flashes the update window for a split second and the DCS.exe process just gets added to the task manager.
Below I have included a zip of my appdata folder.
I have tried deleting the temp folder as well as the Saved Games folder. No joy.
