Unfortunately your screen capture is too small to read the most important part.  What is the error message under "Configuration not saved"?
 

Make sure you only use a dash - between letters & numbers, no other characters or spaces will work.

More history from the battle, please.

Confirm that you are using this firmware:
aredn-20230605-644b657-ipq40xx-mikrotik-mikrotik_ldf-5acd-initramfs-kernel.bin    renamed pr soft-linked to rb.elf
aredn-20230605-644b657-ipq40xx-mikrotik-mikrotik_ldf-5acd-squashfs-sysupgrade.bin

Others have report a similar issue and had success by using Netinstall with routeros-arm-6.45.7.npk,
then rb.elf, then the sysupgrade.bin.

Hi, there:

This is above-my-paygrade.
Typically, the 'Download Support Data' file should be attached from you device should be attached to your post.
The 'Download support Data' is available from the booted rb.elf instance.

However, I would like to see what you did .vs. your words describing what you did.
e.g.

gelmce@nc8q-acer:/tftp$ ls -l rb*
lrwxrwxrwx 1 gelmce gelmce 120 May 12 09:40 rb.bin -> aredn-3.23.4.0-ath79-mikrotik-mikrotik_routerboard-sxt-5hpnd-squashfs-sysupgrade.bin
