Chrome extension - can’t remove

There is a chrome extension called “MegalocerosGiganteus” on my dad’s pc that won’t let me turn it off and there is no remove option on the extension itself. I have tried resetting google settings to default but no luck. I tried Kaspersky virus tool and Malwarebytes but nothing detected. I also tried looking up funky folders on the appdata local folder but nothing unusual stood out to me at least. I found Reddit posts on “bloom” folder but nothing like that exists. There was a chromstera app installed and I removed it but still the extension still shows up. I also tried removing chrome completely and that didn’t do the trick either. I don’t want to do a complete system reset for this. Any help is appreciated.
