A workaround I can think of (assuming you play on phone or smth). Pick another device (bluestacks for example), and try there, might go right, and then back to your own device, but the tutorial will not come again
Looking a bit closer through the other linked topic it also seems to show up in English, so language settings are unlikely to help. The weird thing is that your shop seems to be missing some tabs, it should actually looks like this:
No “Gems”, no “Subscriptions”, and, most importantly, no “Warbands” tab in your shop, so Luther probably gets stuck trying to move you there. Beats me what could cause those tabs to go missing. Apparently reinstalling doesn’t help, so it’s possibly something server side in your account profile. Open a support ticket, maybe they can at least disable the tutorial for you so you can play again.
Sounds like it’s trying to load the initial shop content, eventually fails with a timeout and then jumps to some old layout page that confuses Luther. That page that loads a long time, what do the tabs near the top say?
A month ago I downloaded and played the game for the first time, and there was no bug. Two days ago I deleted the game, reinstalled it and played from beginning again (using the same google account), and then the bug happened.
