Inspiron G5 15-5590, Ubuntu ACPI error on boot, delay by 10 seconds

​ ​

​ ​

​I've just bought a Dell G5 5590 and installed Ubuntu on it. While it is able to boot, the boot process is taking a long time to finish [10s only showing this message: ACPI Error: No pointer back to namespace node in package 00000000984b3a13 (20190703/dsargs-303)]​

​The BIOS is already updated to 1.11.1 (it came updated).​

​As it has 32GB RAM, 9750H, and RTX2060, 20s to boot Ubuntu seems a long time (my old laptop did better than that).​

​You'll find part of boot info bellow (the error starts at line 314):​
