Name not unique on network error while adding virtual interface

Question

I am trying to add an virtual interface type AP for my TP-Link TL-WN722N on Ubuntu 16.04 LTS. Below is the command I used

vinay245@vinay245:~$sudo iw dev wlx60e327078eed interface add wlan0_ap  type __ap 

There are no issues which creating this I think, however when try to bring up the interface, I get below error

vinay245@vinay245:~$ sudo ifconfig rename4 up;
SIOCSIFFLAGS: Name not unique on network
vinay245@vinay245:~$`

I am not sure how to resolve this. I have below additional for quick reference

vinay245@vinay245:~$ iw dev
phy#0
Interface rename4
  ifindex 4
  wdev 0x2
  addr 60:e3:27:07:8e:ed
  type managed
Interface wlx60e327078eed
  ifindex 3
  wdev 0x1
  addr 60:e3:27:07:8e:ed
  type managed
  channel 1 (2412 MHz), width: 20 MHz, center1: 2412 MHz
