Ah okay this is sadly just a general browser error. Most likely the RAM memory was full (I can see 84 tabs open in Chrome, that alone eats a lot of memory).
Try closing most of those tabs and reloading, could help a lot.
But I’ll launch the android version this week probably Thursday. Standalone android app should run way better on your device as you don’t have the overhead from the other tabs in the browser. It will be on this site to download.
