The error is self-explanatory, the destination folder that you choose is NOT writable.
It is really BAD IDEA to install AmiBroker into "OneDrive". You should install it to LOCAL HARD DISK, that is NOT touched by OneDrive.
OneDrive is going to get you a lot of trouble, because it is not designed to handle DATABASES. OneDrive is meant to be used with single files like Word doc, not high-performance databases like AmiBroker.
