Duplicate packages in the guest OS when bridging to the LACP adapter in Windows

Description
In VirtualBox version 6.1.32, when using a bridge to the LACP adapter in Windows Server 2012 R2, duplicate packages appear in the guest OS.
Tested on Debian 11 using ping.
The host PC running Windows Server 2012 R2 is connected to the router via a Zyxel GS1900-8 switch using the LACP protocol via 2 Intel I350 NICs. If you send a ping from any guest OS, for example, to a router, then several packets will be returned in response - 1 + 3 duplicates. At the same time, there is an increase in the load on the CPU and RAM of both the guest OS and the host OS, respectively.
Previous versions of VirtualBox did not have this problem, including 6.1.30.
The versions of the expansion packs used were the corresponding versions of VirtualBox.
VMware Workstation had the same problem for a long time, and now it has reached VirtualBox. :(
I tested this effect earlier in VMware Workstation Pro 16 with Linux and Windows guest OS - the result is the same, there are duplicates.
When installing an extension pack from version 6.1.32 in VirtualBox version 6.1.30, then trying to start the VM (unsuccessful due to version incompatibility), deleting the 6.1.32 extension pack and installing the 6.1.30 extension pack again, something breaks in the hypervisor and duplicate packages appear in all guest OSes.
Repairing VirtualBox 6.1.30 from the installation file and then rebooting the host machine helps.
