Answer 1

Delete the AppData/Roaming/Docker greeted me with the Docker Desktop welcome screen.

By deleting features.json file from C:\Users\Username.docker my docker desktop is starting.

Answer 3

It happening just because corruption of some JSON files. You need to update the following JSON files as all these file filled with null values - ~\AppData\Roaming\Docker

• forwards.json
• settings.json
• locked-directories

Also you need to update C:\Users<username>.docker\features.json.

PS: You can take these files from one of your colleague/friend (as I did)
