Guys, guys , guys the worst nightmare for a new user of Unreal engine is the packaging errors and the funny scratching party each time you get a lack of memory because of the 99999 tasks of the OS. Can you lock 5 years on your planning to replace the error message “Unknown error” by a human message so we can guess on which blueprint we have to focus please ? ---

Ok in your log console, the error this time was related to UE 5.3 : “BuildException: Microsoft platform targets must be compiled with Visual Studio 2022 17.4 (MSVC 14.34.x) or later for the installed engine. Please update Visual Studio 2022 and ensure no configuration is forcing WindowsTargetRules.Compiler to VisualStudio2019. The current compiler version was detected as: 14.29.30148” So can you highlight please in STRONG, BRILLANT and SHINY PURPLE RAIN COLOR the exact line which explain the causes of any errors in your log console please ? 🧐 ![prince](https://d3kjluh73b9h9o.cloudfront.net/original/4X/6/0/1/6018b8bf860440f185b749a840c9e52d56ca22c0.jpeg) ---
