Hello gattusov,
Unfortunately I was unable to continue looking into it as I hadn’t reproduced it and the users experiencing it stopped responding. Are you receiving the exact same errors that Asher posted above? If not, could you post your error log / output log from Visual Studio? I’m assuming this is true based off the way you worded your message but were you able to compile for these configurations correctly in previous versions of the editor? Have you tried doing this with a project that was created in 4.12 to see if the results may be different?
