[Ufile .u22 files created by Windows 10 can't be opened by my new computer Windows 11]

Hello, I recently replaced my laptop. I found the .u22 files which were created by Ufile 2022 of my old laptop (Win 10) can't be opened by Ufile 2022 installed in my new laptop (Win 11). The error message said - Exception of type "System.Exception" was thrown. What is the error? How can I open these .u22 files? Please help. Thanks.Cynthia

[staycation tax credit]

Hi, I booked my stays via Expedia or Airbnb. There are no HST numbers shown on the receipts they provided. I called them but the agents said they don’t know anything about HST number. Could I skip this HST number field or leave it as 00000000 in Ufile? Is there a way to claim Staycation without HST number? Thanks.
