I try to flash image for Radxa Rock 3C from here: Radxa 3C Ubuntu image
I use SanDisk 64GB flash card. MyOS is Windows 10. The disk is formatted in extFAT.
When I started a flash process I got the error: “User did not grant permission”
There is a console log file:

I ran the software as administartor with the same result. I use ESET antivirus program which I turned off while flashing - it didn’t help. Software version is 1.14.3.
Any suggestions?
