_tkinter.TclError: couldn't recognize image data about ttkbootstrap HOT 4 OPEN

The version of tkinter provided in macOS is probably outdated. If the following code:

import tkinter
print(tkinter.TkVersion)

gives anything below 8.6, you should update it somehow. There instructions on it on the internet.

from ttkbootstrap.

Alright.
So I did update tkinter to 8.6 following this answer: https://stackoverflow.com/a/61879759

Done these steps:

brew install tcl-tk

export PATH="/usr/local/opt/tcl-tk/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/tcl-tk/lib"
export CPPFLAGS="-I/usr/local/opt/tcl-tk/include"
export PKG_CONFIG_PATH="/usr/local/opt/tcl-tk/lib/pkgconfig"

brew reinstall python

make sure version is updated:

brew info tcl-tk

Then created new environment

python3 -m venv myenv

Activate it

source myenv/bin/activate

and run the *.py test file with:

import tkinter
print(tkinter.TkVersion)

So, I moved my projects files into the new environment and issue with not recognizing image data was solved.
Thank you @rdbende for showing which way to dig =)

Yup, same issue here.
Possibly any solutions?

It works on Win10, as well
