This panel takes configuration data from the file '/etc/network/interfaces'. If this file exists at the moment, would you mind posting it?
It's possible that network manager edited the file automatically, or moved the network configuration somewhere else, e.g. /etc/network/interfaces.d.

For Proxmox VE network configuration, you should look at the network configuration sections of our administration guide [1] and the debian handbook [2], in addition to the ifupdown section of debian's wifi wiki page [3]. Regarding Debian's WIFI wiki page, Proxmox VE 7 uses ifupdown2 by default, so after the configuration, you can reload your config in place (without reboot) with: ifreload -a

# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

Which version of Proxmox VE are you currently using? If you have Proxmox VE 7.x, could you try running the command ifreload -a to see if the interfaces file gets loaded?
If it's version 6.x or below, you may need to reboot (or install the ifupdown2 package and run the above command).
 
its Proxmox VE 7.1

this is what i got in the log after using the command 'ifreload -a'

I'm not sure where the 'hash_elasticity' option is coming from, but that message is only informative. Do you see any interfaces in the GUI yet?
If not, could you post the output of ip a?
 
unfortunately no still nothing
this is the output of ip a
