Does not save and does not load game Bug

[peak valley]

The situation where I couldn't save the game or load the game, nothing could be recorded, I believe. I selected to exit and I reloaded the previous saved game before leaving on the trip. I followed the same route of the trip again, and I'm at over 20,800.5 M, and no bug has occurred. It allows me to save and load again. Before encountering the bug, I used the shelter capsule and slept, then I continued the journey, and that's when the bug occurred where I couldn't save or load. I couldn't share the auto-save because when I loaded the previous saved game, I went to sleep and the auto-save from the trip with the bug was lost. I hope this serves as a guide to finding and fixing the bug.

I have discovered the origin of the bug. When you use the survival capsule, if you wake up and exit the capsule quickly, then select (Esc) and go to the main menu, I noticed that I couldn't load or save the game. I continued playing for a few seconds to see if the bug would disappear. I entered and exited the capsule and pressed (Esc) again in the main menu, and everything returned to normal. I was able to save and load the game again. I hope this information helps in reviewing and fixing the small bug that sometimes occurs and causes players to lose their progress.
