I don't think the chipset matters. Apple can use any variety of devices.
I understand you are unable to pair any BT devices though. Follow these instructions: Connect a Bluetooth device with your Mac - Apple Support.
Can my recent update of ventura caused the problem?
I suppose it's possible, in which case you should contact Apple and tell them about it: Official Apple Support. They may be interested to know which devices you are using and what you did toward resolving the inability to pair them, which you did not explain in your question. No one will know what those "other suggestions" are unless you tell us.
