Based on the comment in this diff – https://chromium.googlesource.com/devtools/devtools-frontend/+/20ed4f2bd282537f404af9d45df1333d5aeb21f5%5E%21/#F0, I felt this has something to do with Partitioned cookies. So I opened chrome://flags and set the value of “Partitioned Cookies” to Enabled” and relaunched the browser. After that the red row did not appear and I am able to set the cookies like before.
