Microphones recognized in settings but not while singing

[M4rkusFranz]

Actual behavior

When starting to sing a song the music playback works normally, but my 6 microphones aren't picked up/used.

Expected behavior

While singing I should see. if I'm getting the tones right and get points.

Steps to reproduce

Open Song select.
Press a few times "r" for random songs.
Choose the newly selected song about a second after it was picked. (Usually the first two or three work just fine, but I guess the BASS library is overwhelmed when the preview music from song select and the actuall singing starts immediatley afer.)
The song starts playing but singing doesnt work.

Details

After checking the Error.txt I found the following message every time the problem occurred.
BASS_RecordStart: Insufficient memory [TBassInputDevice.Open]
My Laptop is using an Ryzen 7 7840HS with 32GB of RAM. The RAM utilization is under 40% while playing/testing.

I am using the Soundcraft Ui24r via USB.
The microphones are always recognized in the record settings. So after the first start and after the problem.

I had Ultrastar working just fine, before I changed my laptop. The last one was on Windows 10.
