Already mentioned elsewhere, but take a look at https://www.goethe.de/en/spr/kur.html , search for "Goethe Institut" on Google Maps, consider working with someone from https://www.italki.com/en/teachers/german , search for "learn german" on YouTube, etc.

Babbel was mentioned a few times, Pimsleur as well (they're different companies/methods), https://www.languagetransfer.org/ ...

Mix and match to find what works for you - what seems fun and motivating.

Oh, and consider informal irl meetings as well - https://www.meetup.com/topics/german/ (depending where you live ofc)
