Virtual Chem Lab opening up blank

Whenever I open virtual chemlab, the tab opens but only shows the very top bar of the tab. Everything else is invisible, but I can still click on things as if they are actually there. I have no idea what I should do about this.

Ah- looks like you are using the new Beta OS Big Sur.
Many programs won’t run on Big Sur, our old version included.
We have created a test app that has worked on our big sur version, but we aren’t 100% sure it will work on all devices yet. Please feel free to submit a support ticket on our support page:
We can send you the trial Big Sur version from there.
Or just use Boot Camp to boot a stable OS and the program will load just fine from there.
