I have a lot of entries in Canvas modules. when I try and edit one of the entries, it crashes the browser. When the edit box opens and I try to edit, the screen fades with a spinning circle. The browser then freezes errors out.  I've tried every browser; the same thing happens so this is not a local issue. I've cleared the cache and history to no avail. There is something wrong with Modules that causes the program to crash. I don't know if there is a limit to the number of modules/assignments that would cause this. I sense a size issue. 

I am an instructor and have been using Canvas for many years. This problem started about a month ago. The school does not know what would cause this.
