probe of spi0.0 failed with error 1

[maxlacourchristensen]

With:

• RPI4B-
• Ubuntu server 22.04.03 LTS (kernel 5.15.0-1034-raspi)

After calling:

sudo dtoverlay dts/nrf70_rpi_interposer.dtbo
sudo insmod nrf_wifi_fmac_sta.ko

I get the following error in dmesg. Any idea why this is?
/boot/firmware/config.txt has dtparam=spi=on
