I found an old thread discuss a similar problem
Binance tempararly blocked my withdrawal because i changed pc also due to large amount withdrawal too, probably you're using VPN to access Binance don't you?
Probably you will get a same answer if you contact the Binance support to solve this problem, they will ask your KYC to confirm if you're not breaking their TOS and proofing of your ownership, this is not something new if an exchange ask KYC whenever you want to withdraw large amount money.
As per checked, we found that the withdraw function was suspended due to the withdrawal risk control.
