PLEASE HELP!! Animate FLA files disappearing off desktop folder

Put this into an older post but the persons problem was slightly different then mine and was nt sure if it would be seen where it was.

.  After spending a couple hours in Animate on small projects over the weekend all 3 dissappeared from a folder i was saving them into on my desktop on my M4 macbook.  And not at once. So I don't understand what Im doing wrong.

 I did one. Saved it. Was able to open it again. Later in the day it was missing from the project list when opening the program. It was in the recent opened list, but when i tried to open it from there it told me it didnt exist and would remove it from the recent list.  This happened 3 times in a row.

The only thing I can think of is maybe i opened the project and closed it again without making a save but Im not sure if i did that all 3 times.  And no other program works like that so it doesnt make since for it to dissappear.

I am new to animate so would love to just hear that im doing something little wrong.  I have checked the trash bin and cloud folders. 

The lost files were tests and tutorials so im not worried about the loss but dont want to continue creating until i know i wont lose it.
