I scanned a friend's NFC tag today (it unlocks a door) and I was able to save it without any problems. When I tried to access it though it prompted me with a 'file couldn't be parsed' error. Later today when I was home I connected my flipper to my pc and took a look at the .nfc file. The Device Type was Mifare DESfire. I didn't see a problem with the file itself or the contents, so I asked in the help section of the Flipper Zero Unofficial Discord. A guy called miga screwed a bit around with the information I gave him and he figured out that if you change your device type to DESfire Mifare on any .nfc file it brings up the same error. So I am not sure if it is intended to be that way or if simply I made a mistake and him only editing the Device Type made his file corrupt but I just wanted to let you know to see if this is a bug or not.
Reproduction
Turn on the Flipper
Head to the NFC tab
Select Read
Read a NFC tag (Mifare DESfire)
Save the tag
Access the tag through the 'saved menu
Upon opening the saved .nfc file you should get prompted with: 'File can not be parsed'
You can analyze the file itself aswell.
Target
NFC - Mifare DESfire
