Problems setting up LAGG with VLAN to switch

[wk87hop]

Probably just a noob configuration error but I'm really stuck on this... I am trying to setup a standard 2-port LAGG between my OPNSense box (virtualized in Proxmox) and my Cisco SG300 Switch (L2 mode) following this guide: OPNSense (https://www.youtube.com/watch?v=h2_cQxTkh3Q&t=1868s) & switch (https://www.youtube.com/watch?v=4HP-YAJX56E&t=370s). I am trying pretty much the same settings, just with Management VLAN 10 ("ADMIN") instead of 1.

I currently have everything setup but cannot establish connection between the devices (ping fails from both sides). It doesn't seem like the LACP is working correctly, as I can see "active ports: 0":

Also, on the switch I can see that one of the two ports is in standby: https://picallow.com/81567-2

I also cannot reach OPNSense on my computer which is plugged into an untagged VLAN 10 (Management "ADMIN") port on the switch.

These are my settings in OPNSense: https://picallow.com/36936-2

And these are my settings on the Cisco switch: https://picallow.com/60026-2

Can anyone spot the problem? Thanks.
