When I do symfony self-update I get the following error - how can I solve it?
Backup failed, rename D:\SERVER\Symfony\symfony.exe C:\Users\FairyWilbury\.symfo
ny\autoupdate\2019-07-19_14-57-14-79024bb-old: The system cannot move the file t
o a different disk drive.. Canceling upgrade.
UPD.
I have just realized that the latest symfony version seems to be 4.3 with 4.4 due to release in November https://symfony.com/roadmap/4.4
Yet whenever I run symfony new --full %projectName% it suggests I should update to 4.6 (and then fails to update as described above). Screenshot of the command line: 
What can this problem be?
