Only came here to tell you that if anyone is looking for newest drivers for Sabaj A20d 2022 version you can download drivers for SMSL devices and right now you cen get XMOS 5.58 version and this installs a driver from May 2023 at least for Windows 10 and its significantly newer than XMOS 5.50 which you can get from Sabaj site.
Hopefully some of you can find this useful, peace !
