command line – Bash Terminal showing unwanted text on opening

My terminal is showing the text copied below on opening. I think, though can’t be sure, that this started happening after I installed a theme for the first time. Can you help me to remove this?

My .bashrc doesn’t contain anything that would directly print this text.

I have run grep LS_COLORS . -r from insides /usr/share/themes/ Nothing was matched.

Related: my bash terminal is showing unwanted message when starting (answer not applicable here).

update: The same text displays again after running source ~/.bashrc

Update 2: Dircolors being run in bashrc:

# downloaded feb 2021
eval 'dircolors /home/neil/gnome-terminal-colors-solarized/dircolors'


# enable color support of ls and also add handy aliases
if ( -x /usr/bin/dircolors ); then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
    alias ls='ls --color=auto'
    #alias dir='dir --color=auto'
    #alias vdir='vdir --color=auto'

    alias grep='grep --color=auto'
    alias fgrep='fgrep --color=auto'
    alias egrep='egrep --color=auto'
