I think you're just hitting the limits of working with large capture files.
The file has 33M packets. Splitting the file into 1M packets chunks using editcap -c 1000000 file.pcap out.pcapng
and then running the same tshark output on a 1M file took 144 seconds (i7-8550U with SSD), the tshark process peaked at 2GB RAM and the output file was 3.88 GB.
