Problem recreate windows

[lars44]

Version tmux 3.3a
Platform: Debian 12
screen-256color

Issue description:
I get an error when I want to recreate all windows incl. the ssh command that log in to different servers.
Command C-a C-r loads all windows but without running ssh command (ssh server2 + ssh server3).
Command C-a R shows:

/root/.tmux/resurrect/last:1: unknown command: pane

The last part in .tmux.conf looks like this:

resurrect_dir="/root/.tmux/resurrect"
set -g @resurrect-dir $resurrect_dir
set -g https://github.com/plugin '/root/.tmux/plugins/tmux-resurrect'
set -g https://github.com/plugin '/root/.tmux/plugins/tmux-continuum'
set -g https://github.com/plugin '/root/.tmux/plugins/tmux-sensible'

bind-key R source-file /root/.tmux/resurrect/last
run-shell '/root/.tmux/plugins/tpm/tpm'

What do I need to change or add to get the right action?
Thank you.
