I managed to make a "fix" to the 0% habitability shown and not being able to colonize for either you or AI. Its quite simple so much that this is my first time touching code and it seemed to work.
Just go to your Stellaris folder (should be 281990) within your steam folder (SteamLibrary\steamapps\workshop\281990).

And once your there find the 2264631052 file, its this mod. Next you go in common, then species rights, and in the zzzzzzzzzzzzzzzz_species_controls_overwrites_various_servants.txt (I used Notepad ++ to open and edit the file) you edit the colonization_controls_yes portion of code from

potential = {
always = yes
}

allow = {
always = yes
}
}

To

potential = {
NAND = {
from = { has_authority = auth_machine_intelligence }
OR = {
has_trait = trait_machine_unit
has_trait = trait_mechanical
}
}
}

allow = {
hidden_trigger = { exists = from }
if = {
limit = {
OR = {
has_citizenship_type = { country = from type = citizenship_purge }
has_citizenship_type = { country = from type = citizenship_purge_machine }
has_citizenship_type = { country = from type = citizenship_slavery }
has_citizenship_type = { country = from type = citizenship_robot_servitude }
}
}
hidden_trigger = { always = yes }
}
else = {
custom_tooltip = {
fail_text = same_species_disallowed
NOT = { is_same_species = from }
}
}
}
And it should disable you and AI from using electric collar on your main species which causes the problems outlined above.
(please note I am not a modder and this is litterally my first time editing code by my self, I just have a bit of time and wanted to fix an annoying but easily fixable bug)
