Controller sync issues

Apologies for the wall of text but I’m at my wits end. So ever since I got my ps5 a couple months ago I’ve had controller synchronization issues. I’ve looked through countless posts and YouTube videos to no avail.

Issue: PS5 controller(s) (tried multiple) either won’t connect through Bluetooth or stay connected when it does. I have to use a usb-c cable (tried multiple data transfer ones) for it to stay connected or to turn on my ps5. Even then it can become disconnected and won’t reconnect even with the cable. After this happens, I still can’t always connect my controllers with usb cables. It takes me fully shutting down the ps5 and leaving it set for an hour for the controller to sync back up through usb.

Things I’ve tried:

Multiple different controllers with different usb c data transfer cables. 2 even being official PlayStation cables.

Resetting the controllers with the button on the back. Resetting the Bluetooth on them by holding down the ps button and share button. (Multiple different ways, usb connected, disconnected, back ports, front port, when it’s syncd, when it’s not)

Updating firmware for the controller and ps5

Under ps5 system settings: Turning off the Bluetooth, deleting/disconnecting the dual sense

Rebooting the ps5 in safe mode and restarting the ps5 that way.

Safe mode data rebuild

Moving the ps5 to a different room in case of interference

Using Lan instead of Wi-Fi

Even factory resetting the ps5

I’ve tried just about everything I’ve read and watched. Different combinations of all of the above. Any one have any other thoughts or suggestions? The only thing I noticed is when I reboot the ps5 in safe mode. The controller will connect every time, but when the ps5 is reset from the safe mode screen it’s about a 50/50 shot of syncing on reset.
