Hi ,
Currently in Microsoft Q&A we only support English, you may reply us in English and we can continue this thread discussing. I have translated the language to English as below:
We used an expression (addDays ('1899-12-30 3: 00', int (items ('Apply_to_everywhere')? ['Start Date']), 'yyyy-MM-ddTHH: mm: ssZ'), and it worked until last year, but we started running the flow today (01/13/2021) and there is an error in this expression.
Microsoft Flow is currently not supported in the Q&A forums, the supported products are listed over here: https://learn.microsoft.com/en-us/answers/products (more to be added later on).
For the related questions about Microsoft Flow (now called Power Automate) you can ask in here:

Best Regards,
Candy
