I've met the same problem, and the version of solidity is 0.8.4 I tried to add a variable like this offset, _length, file_id, _, x = mapping_item and another bug occurs

File "C:\Users\ruby\AppData\Roaming\Python\Python37\site-packages\slither\analyses\evm\convert.py", line 131, in _get_evm_instructions_node
    node_info["contract"].source_mapping["filename_absolute"],
  File "C:\Users\ruby\AppData\Roaming\Python\Python37\site-packages\slither\analyses\evm\convert.py", line 189, in generate_source_to_evm_ins_mapping
    mapping_item[i] = int(prev_mapping[i])
ValueError: invalid literal for int() with base 10: '-'

then I tried to add codes here (around line 186 of convert.py)

       for i, _ in enumerate(mapping_item):
            if mapping_item[i] == "" and prev_mapping[i] != '-' and prev_mapping[i] != '':
                mapping_item[i] = int(prev_mapping[i])

Now it works, but I don't know why it works or whether it works correctly
