Laptop wakes immediately after suspend on kernels newer than 4.19.102

The suspend function does not seem to work on my laptop. It wakes up 4 seconds after suspend:

$ sudo journalctl -f -u systemd-logind
Feb 16 16:54:02 dimura-laptop systemd-logind[683]: Lid closed.
Feb 16 16:54:06 dimura-laptop systemd-logind[683]: Operation 'sleep' finished.
Feb 16 16:54:13 dimura-laptop systemd-logind[683]: Lid opened.

I get this behaviour on kernels 5.5.2 and 5.4.18. If I downgrade to 4.19.102 - suspend works, but the WiFi adapter does not.
Laptop config: Lenovo Flex Pro 13IKB, Core i7-8550U, WiFi: Qualcomm Atheros QCA6174 802.11ac

How do I find out, why the suspend does not work and fix it?

Sorry, tried that, forgot to mention in the first post. It did not affect anything for me,

$ cat /proc/acpi/wakeup | grep enab | wc
      0       0       0

I decided to try booting from the new manjaro KDE 19.0.2 live cd, and, surprisingly, the sleep mode worked perfectly. So I guess my problem is solved. The kernel version was 5.4.23, by the way.
