Posit Cloud logging out when loading up an excel file

I am teaching an introductory DS course and we hit a brick wall today in class. I assigned a group project that required an excel spreadsheet that is 42mb in size and has 4 tabs. The file can be uploaded to Posit cloud but every time we tried to read one of the sheets into a variable we would get logged out after about 30 seconds. It happened for everyone.

I tested the file on my local RStudio before giving it to my students and everything worked fine.

I am paying for a plan to where this should not be an issue in terms of size of the file.

Any ideas on what it might be?

"login expired or signed out from another window....."

There was a similar thread earlier but it didn't have anything to do with loading up an excel file. Everything is fine until then and we had never had this error until this project.

Thanks for any thoughts you might have.

FYI - Converted to a CSV file and it worked fine.

I also have the same problem. You can convert the file to csv or increase RAM of the project.
