I assume you tried the methods you found with https://www.google.com/search?q=empty+trash+bin+mac to empty it (delete all files at once) and none of them worked. Can you tell the errors given by those methods.
Then all that rests:
- Can you delete individual files from the trash bin?
- Can you delete 100 files at the same time? Then the issue is nearly solved (just repeat 1660 times).
