Match History Broken After 5.4

As of 5.4 I have received a 401 error whenever I try to access match history. I am neither able to access my own history or that of others, the entire platform is unavailable to me. I have tried clearing cache, cookies, logging out and back in, switching browsers AS WELL AS trying to access my page by searching my summoner, and releasing and renewing DNS to no avail. I have further tried to access the platform on other devices such as my tablet, phone and laptop and have been unsuccessful. This leads me to believe that the issue does not lie on my end and instead somewhere else. Another error outside of the 401 error that I've seen outside of directly trying to access my page is Error 500. I would appreciate help in resolving this issue. I have attached a screenshot to further credit my issue.

I am reposting this issue a second time after having received no feedback on the forums previous. I have contacted player support and despite a suggestion I still have seen no resolution in this issue.
