Hello! I'm here to help you! :)
What OS are you using? Windows? Android? Which version?
Ok! I've made some research...
This issue (missing api-ms-win-crt-convert-l1-1-0.dll) can occur when the computer system becomes overloaded or important program files disappear, are accidentally deleted or get corrupted. These types of defects can occur on computers that do not undergo regular maintenance, which can lead to critical failures and system malfunctions. It may be possible to resolve DLL issues with special software that repairs system elements and adjusts system settings to restore stability.
This is what I found... I don't know how the maintenance of your PC is going. But let me ask you. Are you having the same issue when you try to play other Ren'py games?
