Thank you zwerg2000. I bought a Realtek RTL8192 usb wlan adapter. With this adapter on Ubuntu 20.10 now association works.
Association fails with a Qualcomm qca6174 hw3.2. This issue is still present on Ubuntu 20.10. The issue might be in wpasupplicant or the underlying kernel driver since it is hardware specific.
