Davinci Resolve crashing

Hello everyone, Now 2 months ago I downloaded this thing called BBC. after I did that I tried loading Davinci Resolve 17 beta up and kept crashing Now i go to uninstall the BBC Plugin that I got from Xen Joshhy { a Davinci resolve pro editor } and I restart my pc and still wont work I've watched videos on how to fix it and yet still won't work I don't have a clue what to do, someone help me please.

How about giving us some details of your computer for a start. Include details such as OS, ram, GPU and its driver version, etc. You can never give too much information.
What is this BBC plugin supposed to do?
