Hi, I hope you got the mod installed properly by copying everything from the folder to your game directory.
Here is a solution for your issue :
1. Don't run the C-VALORANT.bat file as admin.
2. If you do want to run it as admin then make sure to go to the properties of both 'hl.exe' and 'vstdlib_c.exe' then in the compatibility tab, check 'Run this program as administrator.'
