I'm facing similar problems with i.MX8MN EVK and u-blox wireless SDIO
module with 88W8801 SoC and mwifiex_sdio driver for linux 5.15.28 kernel.
I tried firmware 14.68.36.p204 and 14.68.36.p60. I'm not able to establish
a WPA protected link using wpa_supplicant.

You mentioned that you have tested with 14.68.36.p160 and 14.68.36.p146
firmware versions without having issues in STA mode. Where did you get
these firmware versions?

I was not able to find them neither in linux-firmware, mwifiex-firmware
nor imx-firmware repositories.
