[Windows] Import doesn't work

[PetbkA]

AW: 0.11.0.
OS: Windows 10 LTSC (version 1809) x64.
Browser: ungoogled-chromium 92.0.4515.107.

Today I've updated ungoogled-chromium from 89.0.4389.114-1 to 92.0.4515.107, that's theoretically built from the same source code by other developer + "Safe Browser" functionality isn't cut off.

I didn't expected that the settings will be lost 'cause I didn't change my browser, but they were lost.

Luckily I had exported settings but importing them doesn't show any activity or difference - there is even no activity in the Network tab of Chrome DevTools. Logs also doesn't contain any records about import.

Here's the attached and pretty-printed settings (some sensitive info has been cut off w/o loss in constistency)
