Well, the original post is over 2 years old, but there are other people experiencing the same issue that posted in 2021.
I have a Roku Express, maybe a couple years old. Can't tell you the OS version since it won't get to any point where I could look it up. Model: 3900X.
If you are updating to OS 11, there may be a bug in the release that is causing your issue.
Tagging RokuDanny-R so that he can help you personally.
Go online to https://my.roku.com/account and near bottom of page, make a note of your model number and serial number which is probably what will be requested of you.
They will be able to get you back up and running.
