Hi all,
I just wanted to share that the supported MSVC compiler version in UE 5.3 is
14.34.31933
If you are using the latest version instead of that one you will get this issue.
Manually bumping the version check in code is not advisable. By doing so it means you will be using a compiler version that was not validated with that version of UE, which might cause issues.
You can install specific compiler versions using the visual studio installer, in the individual components tab.
If you installed the recommended version and still can’t compile, let me know and I can check with the team.
