LoadConfig() takes too long on Linux

I’ve encounter issue with my .ini config takes a few hours to finish loading on Linux. Config load triggered by CDO initialization and performed once. There are no such problems on any other platforms.

Config contains a few TMap<> containers and has size of 5mb.

Removing data from config fixes issue. But, if its saved again by running application and LoadConfig() triggered on next launch, application will stuck loading in same way.

Changing TMap<> to TArray<> also fixes the issue. But it’s not perfect solution for me.

Loading stuck in the loop: PropertyMap.cpp:787 (FMapProperty::ImportText_Internal)

Callstack

Any help would be great.
