Is it possible to change University after my biometric where i didn't attend the visa interview?

I have completed my biometric on 13th Dec 2022 and i have visa interview on 19th Dec 2022.Now
Suddenly I received a mail saying that the students are allowed with visa approved before 16th Dec 2022 and after 16th Dec 2022 they are going to cancel the i20.
University saying that you can join other course where i am not willing to join that course.
Now what should I do ?.
Can I go for other University or should I wait for summer intake.
