I apologize for any confusion. if i understand correctly, you mistakenly responded to my post about my problem instead of sharing your own.
I'm sorry for that. I don't know your specific issue since we haven't me before, but i will try to help if there's a solution. If you encounter my problem or learn anything about it beforehand , please inform me about the initial solution. Best wishes to you.
