Bluetooth issues with HA BT versus BT BLE

Since the move from BT BLE to the HA BT integration, I have connectivity problemen.
At the moment the BT integration was live, no issues at all and the transfer from BLE to HA BT was without any problem.

But since the last few HA updates I have to restart the HA BT every 5-10 minutes otherwise all the BT devices are not available any more.

The strange ting is, that the devices are still available in the BLE integration. So it looks like there is an issue with the HA BT integration.

Is there anything I can do to solve this problem?
