The crash occurs in src/gui/views/list.rs at line 348 with an index out of bounds error. Start by examining that file to understand the data structure being indexed. The log shows errors from src/core/utils.rs related to uninstall commands. Reproduce the crash by running the GUI and performing an operation that triggers the panic, then trace back to see why the length is zero when index 333 is accessed.
