Can I enter Bolivia in the same year after using my 90 day visa?

I entered Bolivia for 90 days in May of 2019 to visit my wife and in-laws. I came back in August for school, and want to go back again this Christmas for about a month in between school semesters. I have a specific purpose visa as well, and am wondering if I can re-enter Bolivia either on my tourist visa or my specific purpose visa? Could I just buy another tourist visa? Or is there some other type of visa I can obtain to visit again this year?

Also, if I go and they do not let me enter, what will happen to me? Will I have to find another flight out or could I be arrested?

Thank you all in advance!!!
