I got your point ut this issue only came with this version specifically. I cant even sideload this zip. So I thought the issue could be rom related and not twrp related. Ill be flashing 20.3.26 again to get system back then try again. But it seems anther user had this issue too with miui 12 on this forum.
Also; flashing another older ofox versions have trouble decrypting Internal storage on lavender sice 20.3.5 q update. So another recovery probably wont solve this.
