Where did my disk space go and why can't I analyze it?

I am using ZorinOS lite mainly for rclone. The PC mainly hast the job to copy/ sync Files from one Cloud to another. Also a few very important business applications as the tabletop simulator for example are installed. Now I See that my 240GB SSD is already almost full. Using sudo baobab I can see that most space is taken Up by the /home/pc directory. But I can not analyze much further. I could imagine that rclone has something to do with my problem but I can't seem to get any more information. Here ist the result of the sudo baobab command: Also using sudo du -h /home/pc | sort -hr | head did not give me any useful information about where the majority of my disk space has gone. Now I would like to know what ist the exact problem and how to solve it (delete temporary Files (maybe created by rclone?)). Thanks in advance for any help. I am not very experienced in Linux systems so easy understandable answers are appreciated. Edit: Using the command ls -la /home/pc I am getting the following Output:
