Below are some suggestions you should try:
According to your garuda-inxi output you are using the following wireless adapter and driver:
With the RTL8822CE WiFi/Bluetooth combo adapter, the following driver is generally recommended:
rtw88-dkms-git
If you do not have the rtw88-dkms-git driver installed, you should issue the following command to install this driver:
sudo pacman -Syu rtw88-dkms-git
Usually further configuration steps are required to get the rtw88-dkms-git driver working reliably.
I believe recent versions of this driver automatically blacklist the in-kernel driver modules, but you may want to double check that a blacklist file was created:

If you haven’t done so already, you will likely need to create a driver options configuration file or possibly add a kernel boot parameter to obtain the best reliability from the RTL8822CE wireless adapter.

Sometimes resetting the bios to the factory default can help with the symptoms you’ve reported in the past. Boot into you bios setup utility and revert your bios to its factory default. After the bios reset is complete, power down and remove all power sources from your laptop. Let your laptop sit for 5 minutes without any power. After this, power up and enter your bios setup utility. You will need to alter some bios settings from the factory defaults to make your laptop Linux compatible. The most important ones are to disable fast startup and secure boot. Also be sure you have not enabled raid, RST, or optane, and only enable AHCI in your bios.
After completing the BIOS alterations, boot into Garuda and test your Bluetooth for proper operation.
You may want to try replacing the Bluetooth management utility bluez with blueman to see if there is any improvement. This switch sometimes helps Bluetooth users connect more reliably.
To install the blueman package, issue the command:
sudo pacman -S blueman
