Could it be that your code was getting called multiple times or in multiple threads? I'm not sure but I can imagine that with Selenium. You might want to search for "thread-safe singleton" in Kotlin when trying to fix it again, quite possible the object approach isn't by default, but I'm sure there's an easy fix.

Ah that is a good point to make. It is possible I set it up with parallel running without thinking about it! Will do and thanks for the tip!

That makes a lot of sense. Thanks Cihat for the explanation. Although, kotlin object is actually thread safe. kotlinlang.org/docs/object-declara...

That is what I thought, but if it is spinning up multiple threads, maybe that is why it is spinning up multiple browser instances. I’ll have to look into it again when I get time away from Android studies lol.
