Bluetooth / Internet issue

OS Build 19042.746
I have an issue with my internet / bluetooth...

If i turn on bluetooth, all the wifi networks are unable to be reached...
But if its off, Wifi can be reached again...

Is there a way to fix this ?

See if changing the router's Wi-Fi channel will help.

See if changing the router's Wi-Fi channel width will help.

See if changing WiFi’s frequency to 5GHz will help.
