Please explain your issue is in as much detail as possible.
First, this is my first post and the very reason why I'm here, I'm not am expert on Stellaris mainly play casually for fun so maybe there is something I missed, also I don't know how to find the version number and checksum required above. (And off to a good start I already posted on the wrong paradox forum)

Now the actual bug report:

During my cybernetic ascension I noticed one of my leaders species icon changed, at first I thought it was just weird, then I noticed all my leaders changed along with my main species, quite upsetting but whatever I guess it's just a visual bug, but then, after I think the latest cybernetic situation change I got a crime up notification on my capital, which is weird, empire capitals don't have that unless there's a criminal syndicate, then I cliked on my captial world and checked the pops tab only to find all my pops being purged with no way of changing the species rights, after that I noticed my "new and now purging main species" was a totally different name, and now my "original not purging main species" is now growing back on my planet, didn't check the other planets since I assumed my playthrough was lost with this giant setback and now I'm here. I did tried reseting the game but no luck.

I'll attach the files required for a bug report since they seem to help figuring this out along with a screenshot of my last time playing the save file but no idea if I should zip the entire log and dump folder or send something specific (the dump folder is empty for some reason so I won't upload the file).

Steps to reproduce the issue.
I have no idea how to reproduce that since this is my 3rd run following the same ascension path with the same empire and this seem like a rare bug, I did some research and found this happened before but with the psionic ascension and the post about it can be found on steam https://steamcommunity.com/app/281990/discussions/0/1697167355216074895/

I just had the same thing happen to me. My pops are gradually being replaced by random species during the cybernetic ascension. Kinda killed my game.

Granted. I am running (many) mods, but the code that branches your pops into a new sub-species and replace them is native to the base game.

Same here with only UI Overhaul Dynamic as mod and with all DLCs

I found the bug. I analyzed the save, it is clearly related to the use of global dynamic event targets. The problem is, another empire had the same situation before you, and somehow your dynamic event_target was not that dynamic and got overwritten (which sounds strange because your event is newer, your species has ID = 1 and the other one ID 11) So I looked in the code where this happens, it is clear from event cyber.3 (and probably the same for Hive cyber.9). The scoping to the dynamic species target is both times really strange. But the real reason is, both events use the same dynamic global target name but with different scope types. So the Hive uses country scope and the other species, the Cyber Hive in your save has country ID = 1...
Using global targets is always risky (and also minimal more performance intense than local targets) and should only be used if really needed, I guess these events can also work without this.
A fix will be probably in Ariphaos Patch soon.

Here is a temporary fix on Steam:

Just started playing Stellaris again due to the new DLC after not touching it for a long time - tad confused since the steam mod above claims the issue was fixed, but I believe I've just had it pop up.
Decided to go down the cyberization route since it wasn't a thing last time I played and noticed my leaders were all suddenly morphed into the same race as my biggest neighbor and I've got a new population growing.
Haven't checked if the purging nonsense was going on but considering the similarity I assume the same bug or something similar is back(?) if it was fixed.

Edit: Went back and checked, population replacement / unhappy "new" population with an alien races traits was indeed happening on my planets - so that fairly long game is in the bin now.

No mods installed for what it's worth too.

Same here.
This is still an issue in 4.0 (no mods used, pure vanilla, all DLC except Astral Rifts installed).
It happens at the 50% mark of the situation.

Any official reply from PDX on this matter?
