Could you please test text expansion in TextEdit specifically? When you try to expand your snippets in TextEdit, what behaviour do you see exactly?
Does the issue of partial expansion / pasting the current clipboard happen only in a particular app, browser window, etc? If you can narrow down the exact scenario where the issue happens, you may find that it's in a non-native app or browser that's being weighted down by plugins that slow it down.
You can try slowing down key events:

@p3av8r That'll be the next step then, establishing which plugin is likely interfering.
I use Alfred's snippets in Gmail in Safari (no browser extensions) on Big Sur hundreds of times a day, so I'm confident that when nothing external is interfering, your snippets should work perfectly.
