Installer hangs at random time

[MasterGroosha]

Hello. I'm using Prestigio SmartBook 116A (PSB116A)
Processor: Intel Atom Z3735F

That SmartBook (which is really a tablet in a form of laptop) was using Ubuntu 19.04, which I used to generate my own .img file using the following files:

OS: Camd64OS_R72-11316.B-Special (Arnold's)
Recovery: chromeos_11895.95.0_eve_recovery_stable-channel_mp.bin
TPM: swtpm.tar

Image written to SanDisk 32 GB Flashdisk. Booted fine, but some time after booting my machine hangs completely. For example, here:

And sometimes even earlier!
Any clues?
