I created a backup of a KiCad 5 project (designed using version 5.99) and then opened it up in KiCad 6 (version 6.07 specifically). When I pull up the PCB or schematic there is a message that I’ve opened up a file from an older version and that it will be converted to the new format upon saving. Unfortunately when I go to save either file I get the error message below. I’ve tried running KiCad 6 as an administrator and that didn’t help. Has anyone else experienced this issue or have an idea of how to resolve it? I’m not sure if it’s a bug in the software or some issue with Windows 10. It happens on two different computers of mine running this OS.
