@fyr, welcome to this forum!

You likely have an installation or related issue with 2 effectively commercial software: Intel’s Parallel Studio XE 2020 product with Microsoft’s Visual Studio 2019, both rather complicated pieces to get installed and configured right on Windows OS.

Please see if this guide can help: Intel® Parallel Studio XE 2020 Installation Guide for Windows* OS

You may also want to inquire at the Intel Fortran forum:

You can install intel’s newest OneAPI toolkit which is free and support VS2019, it has everything you need. There will be no more parallel studio from now on if I remember correctly,

Just install the base toolkit and the HPC toolkit there.
