IIS WordPress 5.6 Multi Sites file upload hang

Hi there,
I am also facing this issue from past 3 days. Whenever I try to do this on windows IIS, it stops working. It was kind of really a great headache for me that sucks. In the past with version 5.5.3, I was kind of frustrated with the bugs that I got in it. I am really confused now that how can I do it on my own. I am shocked that this question is still unanswered. Or do I need to make another thread for this?

Thank you @drosmog! This bug has been killing me. I made the change you suggested and everything’s working at least temporarily while a proper solution is worked on.

Hi everyone,
This thread saved my website. Here’s the code I built into a plugin thanks to @cxdone for the mention, It seemed to work.

I can’t guarantee this will work for anyone else but am hoping the code will provide reference for others later.

Note this is only a bypass of the issue. If the plugin is deactivated the problem returns.
