Run-time Error '3340'
I have the same problem unable to unrecognized data format ( run time error) . Seen you note about removing updates how do you do this? My problem is only one file in access, Microsoft team made a repair, reinstall new update from office 365 and did not resolve problem. Microsoft said they do not know how to fix access application and to contact developers at access are your people able to help me with my file.
Microsoft told me that they do not have any advice they can give on Access issues .... which is remarkable since I pay Microsoft a subscription for their product. I was advised to go to the Access developers forum and I learnt there that I had to uninstall one of the Microsoft updates that they unleashed on the world. This was KB4484127. Once I did this, I no longer had the problem. Hopefully this will do the trick for you too. Good luck.
