I’m having the same issue. Any advance on the solution?
I’ve read in another post that changing some code (curly brackets) the issue can be solved; I’ve changed several curly brackets and still I’m getting the error. I’m on PHP 8, and I think that the problem is related to php version and the phpexcel version used. The plugin should be updated to PHPSpreadsheet, any idea when can that happend?
