Object not found

[BRIGHT-YHZ]

Hi everyone, I'm a new user of vscode-R and I'm encountering an issue. When I connect to a Linux machine via SSH and start an R terminal, I try to read in a large dataset (around 12 GB). However, a few minutes after importing the dataset, the object disappears. I've tried several times, but the problem persists.
Interestingly, when I start an R session via Bash, the dataset loads successfully and remains in memory.
The Linux machine has 377 GB of RAM, so I believe memory limitations are unlikely to be the cause.
