Impossible to get nodes to associate (802.11s) [D-Link covr-x1860]

Hello OpenWRTers,

I have been trying to get 802.11s to work in my D-Link Covr-x1860 (Add support for D-Link COVR-X1860) with brief success.
During the first configuration run I got it working with wpad-mesh-openssl and mesh11sd, however, due to a misconfiguration, I had to re-flash the firmware and start from scratch. Now, I cannot get the nodes to associate.

The configuration is pretty simple. I have used this snapshot (https://github.com/RolandoMagico/openwrt-build/releases/tag/COVR-X1860_Build_20230724) as the device is on the way to be officially supported, configured the br-lan as DHCP-Client in the master and slave nodes, then connect the master node directly to the router via ethernet and the slave node temporarily to the master node via ethernet as well.

After that, I jumped directly to the mesh configuration in the 5Ghz band without much success (tested 2.4Ghz as well). I have tried as many combinations as possible but I am pretty frustrated with the configuration at this point and I would appreciate a helping hand if someone has the knowledge to guide me in order to troubleshoot the issue.

The configuration is pretty standard in both nodes:

uci set wireless.wifinet0=wifi-iface
uci set wireless.wifinet0.device=radio1
uci set wireless.wifinet0.mode='mesh'
uci set wireless.wifinet0.encryption='sae'
uci set wireless.wifinet0.mesh_id=my-mesh
uci set wireless.wifinet0.mesh_fwding='1'
uci set wireless.wifinet0.mesh_rssi_threshold='0'
uci set wireless.wifinet0.key=TestingPassword
uci set wireless.wifinet0.network='lan'
uci set "wireless.radio1.channel"=40
uci delete "wireless.radio1.disabled"

I have checked logread command output as well and I have found some errors in the slave node that may be related, but I am not sure if that is the case or how to fix them as there are no references on the internet. The logread content is as follows:

Where should I start troubleshooting this issue?.
Thanks in advance!

I have tested latest snapshot for the device and everything works.
Thanks.
