im on 5.5, my project packaged just fine last weekend, now i come back and after windows update, try to package same error as you get “UAT: [27/28] Link [x64] game_name.exe
[2025.07.18-02.12.59:638][318]LogPlayLevel: UAT: LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt”.
i have tried re installing visual studio, all sdks, all MCVCs, all .NET frameworks, cleared project Intermediate, Binaries, Saved. regenerated, cleaned, rebuild and fetched from github, tried earlier commits.. and so on.. it builds fine on visual studio but when i try to package in unreal this happens. losing my mind here.
