Producing a few RISC-V chips without any cost/performance/efficiency requirement is easy.
Producing tons of chips with nanometer-scale transistors that are efficient, powerful, and with a reasonable cost-per-unit is very difficult, which explain in part recent shortages. Most companies, even Intel, are relying on TSMC to manufacture chip for them because TSMC has perfected this very difficult task.
I don’t think it’s the production that’s difficult.
Windows doesn’t even run on RISC instruction set I think and so do most windows programs.

Windows actually can run on an ARM CPU so it can do some RISC, but I don’t know if that means it can run on RISC-V or not
