Game wont load from loading screen on some hideouts/special zones

Whenever i go into someone´s cosmic turtle hideout and one more i cant remember the name, the game is not going to load and wont let me in, making me unable to trade to players that have it nor i cant help friends with maps that have it.
Its also happened on starfall crater. Doenst matter how much i wait, game just wont load.

Note:
I play on Steam

Typically not loading instances is related to corrupted files. You can check the client file to confirm any errors and try to Google around the errors that occur when it happens.

First thing to try is Steam file integrity check and see if that fixes anything. Uncommon, but has fixed it for others.

After that is a full reinstall and deleting any leftover files before reinstalling. A fresh slate can rule out a lot.

After that is getting into a lot more technical solutions. Hardware (video card, settings, etc), third party interference, standalone (maybe the issue only happens on Steam, which can be useful for diagnosing something wrong with Steam install), etc.

Unfortunately with each possible fix means having to find someone with the hideout to test it again since Starfall Crate is fairly rare. If any of your friends have the hideout, you can try to join their hideout (while they are online) between each test to see if it worked or not. If not, you may have to bug someone with the hideout to see if you can add them to friends to try to debug. But complicated if they play different times than you.

Good luck!
