VS code indentation mode changes from spaces to tab - visual-studio-code

Question

I am using VS code with a number of extensions, including pylance , editorconfig, prettier, . No matter how many times I change the insertSpaces to true for the different languages or any indentation related settings to spaces mode, at some point (sometimes after a couple of minutes of usage, sometimes after reopening VS code) the tab key starts indenting with tab. I notice this mostly by pressing enter. How can I figure out which extension is doing overriding the spaces indentation mode? I don't want to go through the exercise of testing them one by one. Here's my settings.json that I have pruned down to remove nonrelevant settings.
