It doesn't work as per the error message reported:

tshark: Display filters aren't supported when capturing and saving the captured packets

You can convert the display filter part (-Y ...) to a capture filter:

wireshark\tshark -i ethernet -a duration:60 -f "udp and len>=90 and len <=100" -w test3.pcap
