Works ok for me. Just in case it is a Windows thing, Using Win 10 and Gimp 2.10.8
Check list:
layerfx.py is in C:\Users\your-name\AppData\Roaming\GIMP\2.10\plug-ins
Mossy bark texture.jpg and moss bark texture gray.jpg are in C:\Users\your-name\AppData\Roaming\GIMP\2.10\patterns
Tree_bark.scm is in C:\Users\your-name\AppData\Roaming\GIMP\2.10\scripts
You have your white on transparent active layer over the base layer.
You bring up the Tree_bark script and with default settings the two textures are showing correctly.
Ok the script, it runs & produces a load of layers.
The only real thing I can suggest if you get that error is disable (rename as) the old layerfx.scm.bak
edit: The layerfx.scm does work here but remember that it was made for Gimp 2.6 and hence a little flaky. Remember to work on a layer with transparency and if using text expand the text layer to the canvas size.
Gimp 2.10 uses different layer modes, some thing might not work as expected. Layerfx.py might be a little better, same issue with layer modes. However it is a plugin that I rarely use.
update: tin updated the tree-bark script in case it does not work on your installation.
