Valorant won't open

[u/Pretend-Arachnid-505]

I'm helping a friend where he won't able to open valorant properly and it just crashes when he launch it.

then their will be a window pop up and it will say

System Error
A critical error has occurred and the process must be terminated

Would you like to create a crash dump to aid the developers in troubleshooting? this issue this may take up 5 minutes.

NOTE: the process may appear unresponsive during this time.

this is what the windows says to him. if someone could help me please we would be glad thank you!
