No SSDT-EC.aml or SSDT-AWAC.aml present in your /OC/ACPI folder. These two SSDT's are generated by selecting options 2 and 6 from the SSDT Time option list, after dragging and dropping your DSDT.aml on the Terminal window.

See screenshot below for list of options in macOS version of SSDT Time.

Upon opening SSDT Time terminal command you need to select an option, usually option 1. The terminal command will then ask for the DSDT.aml. Drag and Drop a copy of your systems DSDT.aml, press Enter. The script will run and an SSDT-HPER.dsl, SSDT-HPET.aml and a pair of config.plists will be created in the 'Results' folder within the SSDTTime-master folder.

For your Z390 system you would need to run options 1, 2, 4, 5 and 6.

The three OC config.plist patches generated as part of the FixHPET script look like this in ProperTree for one of my systems:

Given your system is a Z390 your HPET_CRS to XCRS patch would likely be different to the one shown above. The Two RTC_IRQ patches would be the same.

The SSDT-HPET.aml won't work without these /OC/config.plist patches being present and enabled.

Black screen after using the recommended 07009B3E AAPL, ig-platform-id is not uncommon, it is mentioned as a possible issue in the Coffee Lake config guide. The answer to this black Screen issue is to use 00009B3E in place of the recommended ID.
For Skylake, SSDT-USBX.aml is also required.
