Experian credit scores VASTLY different

I keep an active watch on my credit score across almost every platform that offers it. I use the plugins through all my credit cards, Experian app and credit karma. Across every single platform I have a score no lower than 754 and a high of 766.

However, I just hard a hard inquiry pulled for an auto loan, and it was a 690?!?!?!?! I was completely in shock and have no clue why there is such a disconnect. The report says Experian is where it came from, so I really don’t know why it differs so much from Experian’s own app FICO 8 that is currently showing me as a 764 even after the hard inquiry.

Why is this happening?
