Problem creating meme text, previously worked

[padre_two]

I've been using GIMP forever to create meme text (shadows behind the text). My process hasn't changed, but all of sudden today, it's not working. Here are the steps I usually do:

1. Open the image
2. Add text
3. Select the Text layer and select "Alpha to Selection"
4. Select "Grow" under the Select tab and choose size
5. Create a background layer
6. Move the background layer behind the text
7. Select the background layer
8. Select "Edit" and choose "Fill with FG Color"

Normally, it creates a black shadow. Now, nothing. 

Any ideas? I'm using v2.10.36 on Windows 11. 

Thanks!
