Skilled worker visa extension timeline

Hi,
I submitted my skilled worker visa extension application on 12-05-2022 along with my wife and two kids. Biometric registered on 08-06-2022, it has been almost four months and a half but have not got any response from the home office so far. Can anyone please advice if is the normal time frame these days due to the Ukrainian crisis, I am very much anxious.
Thanking you in advance

Now, it takes around 4 months for Standard swv application after Biometric date. Update us when you receive the decision. Thanks
