tmux new-session - not working

[clasher113]

I'm trying to create new tmux session and run another script in it, but when trying to connect to this session it says that no sessions.
I am 100% sure that the boot script is working, because him starts ssh which I can to connect to + all commands in the script are executed if you run the script manually
termux-wake-lock && sshd && whoami && nmap localhost && sv-enable ftpd && sv up ftpd && tmux new-session -d && tmux send-keys ./start-ubuntu20.sh C-m && tmux send-keys ./start.bash C-m
Termux 0.118.0
Termux:Boot 0.7

Please provide information about your device and termux-boot version, and share the boot script (see bug report template)

Add a shebang to your boot script, and make sure the start-ubuntu20.sh script has a valid shebang (i.e. /data/data/com.termux/files/usr/bin/sh instead of /usr/bin/sh for example)

Add a shebang to your boot script

Still "no sessions", though i see the start-ubuntu20.sh script executed and start.bash is running
