Greetings,
I have a Power App with a Combo Box that can filter an Excel Table by giving it text input. It worked just fine in the last few months, but suddenly when I tried to search for something using the Combo Box, it returned this error while showing nothing in my screen:

I thought it was because the access to the Table was closed, but the problem is the Combo Box actually shows a list from the Table when I clicked the drop-down arrow, which made me assume that the Table access might not be the problem.
I also checked the Table just like what's shown in the Error Message, but I don't think there's anything wrong with the Table either.
Is there any other possibilities for why this problem occurs? Thanks in advance
