I'm doing this right now, and at about Month Four I was happy to find myself "talking" in the new language, although the conversations would probably be cringeworthy to anyone but my teachers.

This is without much immersion (due to lockdown then traveling), and the instruction is online, and I've been a lazy bum about additional study.

It's made me pretty optimistic about learning new languages in general, and I'm 50 so the brain isn't exactly a sponge anymore. More like a sieve.
