~username folder appeared in the root of Macintosh HD
Yesterday I noticed a folder appeared in the root of my Mac HD, it has a tilde (~) before my username and the folder itself is read-only. The folder directory goes as: /~simon/Library/Logs/DiagnosticReports and there are no other files/folders in there. Being a perfectionist, I don't want this folder to be there. I searched the internet and there's no record of this issue, solutions on how to get rid of this folder will be much appreciated.
MacBook Air 13″, macOS 10.15
