Miru UI does not appear on Windows 10

Brief summary

I did a fresh Windows 10 (German) install in VirtualBox. When starting the unzipped Miru 1.8.1 nothing happens. The process explorer shows that the Miru process is running, but no window is visible.

Using the installer instead of the zip file did not change anything.

Steps to reproduce

1. Unzip Miru 1.8.1
2. Double click on miru.exe
3. No UI visible, only a miru process in task manager

Miru version

1.8.1

Device

Windows 10 Home, Version 10.0.19045 Build 19045, German
