I think the only one that didn’t was Albania, which just had rampant organized crime and sex trafficking.

Not just sex trafficking, human trafficking in general, also includes e.g. men being forced to work on Greek farms. Plenty of political will to crack down on it but Albania isn't exactly in a state to throw tons of money at any problem.

Realistically speaking the risk as as foreigner is approximately zero, you're much, much more likely to have your pockets picked or caravan broken into. Which might be less likely in say Denmark but also not exactly unheard of. The breaking in part, that is, pickpockets are rampant in any crowded touristy place in Europe.

They're actually close to EU accession but it's tied to that of North Macedonia (because lots of ethnic Albanians in North Macedonia and noone wants to create a mass exodus) and while the beef with Greece has been fixed and the beef with Bulgaria is getting dealt with it'll still take a while. Big-issue items but OTOH it's all ancient history, think about Germany and France getting into a spat because one wants to have Charlemagne all for themselves. Generally a good idea to address that kind of baggage before EU accession which is exactly why states force those issues with their veto but meanwhile Albania is sitting there on the door sill, rolling their eyes while freezing in the cold.
