This issue is usually caused by a homebrew magic item that allows you to cast a spell having it's charges set up improperly. Try removing any homebrew magic items that give you spells, and then refresh the page and try to access your spells again. If it works, you can add back the items one by one to find the culprit. You can then fix the homebrew causing the problem.

The spell page of my character on DnDBeyond on mobile Chrome goes straight to the Beholder with bug error: 5a22765c9ba34bb1916706751b2caf09.
