there has been a fix submitted to Main, but no signs of it being integrated for 4.25 as of yet. 4.25.2 is though scheduled for end of july, lets hope they dont shift it to 4.26…4.25 would be a lost release for many of us then…
in the meantime, you can replace Engine\Binaries\ThirdParty\NVIDIA\NVaftermath\Win64\GFSDK_Aftermath_Lib.x64.dll with the one from 4.24. that solved it for me and some others.
