Events sent with special strings in key places can temporarily disrupt or impede the matrix-react-sdk from functioning properly, such as by causing room or event tile crashes. The remainder of the application can appear functional, though certain rooms/events will not be rendered.
This is fixed in matrix-react-sdk 3.53.0
There are no workarounds. Please upgrade immediately.
