Segmentation fault on startup

[srs4511351]

On a Raspberry Pi 4, the CubicSDR installation went well as it has many times before, but with Debian Bullseye 20210629_raspi_4_bullseye.img, I get a Segmentation fault on startup. The window opens for about a second, then it closes.
I used wxWidgets-3.1.5
I think it may have to do with OpenGL, but I don't know what the problem is.
This is the terminal output on startup. It seems to be like the other installations until the fault.

The next message would be:
Using glxSwapIntervalEXT.

Then it would load fonts, etc.

Any help will be appreciated.

Update:
I wanted to try a newer packages on my Debian Bullseye installation, so I added unstable repositories to:
/etc/apt/sources.list
deb http://ftp.debian.org/debian unstable main contrib non-free
deb-src http://ftp.debian.org/debian unstable main contrib non-free

After the updates, which included a new kernel (5.10.0-8) and some drivers, CubicSDR works.
Since there were many packages upgraded, I don't know which one(s) fixed it.

I am still having serious audio problems, but they existed before.
