Ubuntu 18.04 resume fails after suspending to RAM with 440 & 450 driver versions

Hello,
After I turn my computer on after it was suspended to ram (sleep mode) it shows black screen for a couple of seconds and then reboots (4/5 attempts are failed).
Also sometimes computer may reboot when I close IDEA IDE or Chrome.

Specs:
Palit RTX 2070 Super GRP

Ubuntu 18.04.4 with HWE updates (5.3.0-62-generic #56~18.04.1-Ubuntu SMP Wed Jun 24 16:17:03 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux)
xorg-core 2:1.20.8-2ubuntu2.1~18.04.1

Drivers have been installed from this ppa
The bug affects 440 and 450 version of drivers. 435 works fine
