NATO is not something you can just apply to on a whim. The path for a membership was there: e.g. there were some joint exercises, etc. Obviously they also need political integration as well.
Russia actually have been a member of Council of Europe (PACE, etc.) since 1996 but it was expelled in 2022. If they had a good record in Council of Europe they could really go for NATO membership eventually.
