Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

dmesg shows nothing of ath10k_pci (wifi driver).

Please run "sudo modprobe -r ath10k_pci ; sudo modprobe ath10k_pci" to check whether wifi driver can be re-initialized?

You may want to download and run live session of Ubuntu 20.04.1 ISO to verify whether Qualcomm Atheros QCA9377 works.
