I missed the kalash in the cold lab, am I locked out of it forever?

Is there a way to get it again?

In Atomic Heart, you won’t find every weapon. Instead, you’ll have to build them yourself by trading materials at the shop kiosk. Blueprints are required to craft new consumables, weapon upgrades, and even new weapons themselves. Blueprints are only found in large crate containers — we’ll call these large treasure chests. These chests are packed with materials, and you’ll always find one in every safe room. Safe rooms are recreation rooms with a store terminal and a save terminal. And they always have a large chest.

I posted this in another thread but it seems like there is a random chance to find the Kalash if you missed it (thanks to poster Verdoc for sharing that info). I found it in Testing Ground 6.

The blueprint is in Vasilov before you enter the open world, once you enter that elevator you can¨t go back, make sure you loot every chest in Vasilov.

But there are red doors that absolutely do NOT open. I tried everything, I can see chests on the other side of them but I absolutely found no way to ever open them or vents that lead past them
