Launcher error

Hello. The new launcher that went live for 5.5 isn't working for me. Every time I try it launches a small internal window that displays the following:

An error has occurred on this page

GPU: Nvidia 3080 Ti

Thank you for taking the time to help in advance

Good morning and thank you for posting on the Final Fantasy XIV Technical Support Forums.

To prevent repeating previously attempted troubleshooting, what have you tried to alleviate the problem? Does this issue happen when Final Fantasy XIV is the only program running? Also, could you provide a system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

Thank you for visiting the Final Fantasy XIV Technical Support Forums.
