Virtual controllers created with ViGEm are currently not working
due to an update in PS4 Remote play software
Alleged reason is a special check being added in a software update but i personally can't confirm this.
Another earlier Github issue at DS4Windows talks about the same thing:
https://github.com/Ryochan7/DS4Windows/issues/2868
This bug is replicable without a special setup, i couldn't get past it with 5+ different methods.
I'm currently in search for a workaround aa
