Thanks for your report @hspsconsultants

Do you happen to know if this error occurs on all calls to Excel, or does it work well in some scenarios?
If it works sometimes, can you see any patterns?
I have never seen this type of error, so it's hard to solve in this case. 🤔

I'm also having the same issue, I’ve never been able to use the Export to Excel feature.
