VM’s stop working after creating bond

I’ve got my server all setup, a couple vm’s installed and everything works fine. My nic is a quad port intel 540 with two 1 gig ports and two 10 gig ports. So I decided to try and run both 10 gig ports and create an lacp bond.

I have a unifi 24 port enterprise switch so I aggregate the corresponding two ports, create the bond in pve, add the bond to my vmbr and reboot the server. Now when I go to start a vm it only runs for roughly 30 seconds and when I attempt to open the console of the vm it gives me a timeout error waiting on port 5900.

I’ve insured my nic is running the latest firmware, pve is the latest and my switch is up to date. The minute I revert back to just vmbr and undo the aggregate on my switch everything works fine.

I’m not sure what I’m missing here or doing wrong. Any help would be appreciated
Could you maybe provide us an screenshot how you create the bond in networking and which settings are used?
