You don't have to re-install MIGraphX because it is a package managed by Windows. It is shared between apps so you don't have to re-download it every time.
It seems that AMD users must use the driver version 25.10.13.09 which can be download here : https://www.amd.com/en/resources/support-articles/release-notes/RN-RAD-WIN-25-6-... (Honestly, don't try it if you don't know what you are doing, as updating drivers can sometimes create issues.
Thank you for your feedback !
