Exported image looks different than in Lightroom

Hello,

I'm having an issue with my images looking very different in Lightroom and when they're exported. Immediately when I come to the export screen, the image changes, shadows get brighter and it's brighter and less vibrant overall. I've tried with all 4 available Color Spaces, although I usually use sRGB. There was no significant change. Then I've exported my image as Original + Settings and imported it into Lightroom Classic, exported it from there, and got the wanted result, the image looked exactly the same as in the editor. 

Does someone know why that happens? 

Thank you for the help, here are some images
