As far I understand the issue, it is caused because of a missing dependence in Ubuntu 18.04 on which elementary OS Hera is based on. Wine after 4.5 seems to need libfaudio to be working. You can download it from the link below and use Eddy to install the package (just click on the downloaded file), but remember, this is not an official Ubuntu or elementary ...
So, in order to install it from source, you'll first have to download and extract it to a folder:
Open Terminal and paste the following command:
git clone https://github.com/akiraux/Akira.git && cd Akira
Run meson to try and build the app from code:
meson build --prefix=/usr -Dprofile=default
Look to the output for any missing packages:
