Hey bud, appreciate you and your plugin! I found a bug not sure if already reported but I also found a work-around as well.
A lot of people experiencing OBS freezing on start up with the current OBS version and current backgroundremover version as well.
If you start OBS in safe mode, then toggle the eye for the background remover to off; restart OBS normally then (pay attention) click the toggle eye for the background remover ON AND OFF quickly. It will now be off, but when you toggle the eye a third time, it will work as intended. No crashes yet after doing so either.
Anyways... like to do my part for debug of free scripts I use so there yah go. One free problem, possible solution/starter, and some specs.
Win10, RX580 8GB XFX, Ryzen 7 5700X, 32GB DDR5 Ram, 2 SSD's with one for the operating system specifically. Oh and a 750W PSU, gold standard. Corsair.
Good luck bub, and thank you.
