input 2 integers and getting erorr in pycharm ubuntu

So when i press "Run" and manually input the 2 integers , i get this error down below. I've tried via terminal ,debug and "Run File in Python Console" and it's working fine. I'm running on Ubuntu via VMware. Python version 3.10.4. My code:

a = int(input())
b = int(input())
print(a*b)

Input:

>?2
>?7

Output:

Traceback (most recent call last):
  File "/home/inzein/PycharmProjects/UbuntuTest/test.py", line 2, in <module>
    b = int(input())
ValueError: invalid literal for int() with base 10: ''
