I did a test on my desktop.
Testing process.
2 x rlt8812au
1 x pc ubuntu 18.04

receive.sh

MY_WIFI_CHANNEL=149 #5ghz channel
# MY_WIFI_CHANNEL=13 #2.4ghz channel

MY_RX="wlxbcec238a23a5"
#MY_RX="wlx08107bbfcf00"

sudo rfkill unblock wifi

sudo ifconfig $MY_RX down
sudo iw dev $MY_RX set monitor otherbss fcsfail
sudo ifconfig $MY_RX up
sudo iwconfig $MY_RX channel $MY_WIFI_CHANNEL

sudo ./receive  $MY_RX

send.sh

MY_WIFI_CHANNEL=149 #5ghz channel
# MY_WIFI_CHANNEL=13 #2.4ghz channel

#MY_RX="wlxbcec238a23a5"

Damn. Looks like the rlt8812au drivers still suck. What Wifi Hardware are you using?
To be honest, I can not really recommend rlt8812au/rlt8814au devices so far. I only got a rlt8814au to test and that one sucks.

Injection test from repository uses different COMMID (communication IDs) and also some other parameters are also different. Use "communication" folder examples instead. However I also still have issues with it :)
