DSDT should not be used in OpenCore:

<dict>
                <key>Comment</key>
                <string>DSDT.aml</string>
                <key>Enabled</key>
                <true/>
                <key>Path</key>
                <string>DSDT.aml</string>
            </dict>

you may not need -igfxlspcon boot argument or alcid=22 as you have set your audio up already :

<key>PciRoot(0x0)/Pci(0x1b,0x0)</key>
            <dict>
                <key>layout-id</key>
                <integer>22</integer>
            </dict>

also try booting with -v boot argument to see where it is slow

- Without DSDT battery indicator doesn't work.

- Slow booting happening when I used AirportBrcmFixup.kext

I will try these things now and will post update soon.

Please check attached screenshot, there are 3 stall commands and each one for 60s and I think this is for bluetooth.

you may also need to try adding boot argument:
brcmfx-driver=2

or try brcmfx-driver=1

Updating the kexts worked for me. My bad, the kexts were old. I updated to new releases and it worked.

- Bluetooth is working fine now.
- Slow boot issue fixed, it's booting normal.

Thanks for the help. I really appreciate for you time and guidance.
