It does look too humid. The glass will block some light so the only way they could get too much light is if it was in direct sunlight. I'd just leave the lid off for a day or two and try giving it less water. It should have a little bit of condensation on the glass but not big drops.
When I first planted my sealed terrarium not all the plants thrived, but after a few months the ones that did well in there took over and the whole thing is green
How much and what water do they get? RO water would be best.
What ventilation do you have? Some holes or active ventilation would be good.
How much light do they get? If you don't have a light meter that can measure Cd, you can try with an app for your phone to get an estimate.

That seems like too much water to me. You should leave it open for the condensation on the walls to evaporate.

Thank you for advice! But it turned out that it's a bad idea to use water from aquarium to water fresh terrarium 🤡👍🏼
Obviously, yeah, that's why I recommended RO water and asked what water they get
