@Lim Chong Sun As far as I can understand you are currently on a free subscription. You can correct me if I am wrong.
Can you please check how many credits are showing up in your subscription? If all credits are used up then your subscription might be disabled and that might be the possible reason you are not able to create any azure resource.
You can refer to this for more info.
If the above is not the case do let me know I will help you out with creating one time Free tech support ticket for you.
Hope it helps!!!
