Unable to upload sketch to Mojo v3

It looks like Windows is trying to install some other driver. The drivers should've been installed when you installed the loader but you can try manually installing them again using the "Windows Files" download here https://alchitry.com/pages/mojo-loader

Extract the files and run "dpinst-amd64.exe" or "dpinst-x86.exe" for 64 or 32 bit computers respectively.
