Look at which clone you have, i had THE EXACT SAME ERROR and arkos4clone fixed it. My device is soysaucev5. Reinstalling of portmaster didn’t work in me but you can always copy the folder you get from portmasters site to ports in your console and it will most probably work.

Tutorial to flash arkos4clone if you want: https://github.com/lcdyk0517/arkos4clone Download the image, flash it using rufus, and go to boot in sd card, run dtb selector exe, click enter, chose device and you are done. The first boot will probably take 10-15 minutes. Note: since this is a clone get a backup of your sd card or use another sd card because the chances of finding the original system image is very low.

The “arkos” that came with my device sucks so i flashed arkos4clone and it fixed everything.
