Can't launch any apps after a while (Service not found)

Could you please provide the output of: df -h ? This issue reminds me of this (and a few others similar): If you get something like (100%) tmpfs 0,8G 0,8G 0 100% /run/user/1000 You’d better enlarge your tmpfs as suggested (you could use 4G in your case).
