@Asunción *********
you're asking questions NO one on the group can answer.
Face it, you have an EXTENSIVE entry/stay history here 😮 , All you can do is go try to get a tourist visa from Vientiane or Savannakhet, or another consulate in a nearby country.
Pick a consulate, go to the website, read the requirements, see if it takes an online appt, read the processing time, MEET the requirements and apply.
It'll either work or it won't. That's the only way you're gonna find out
