Vampire: the Masquerade character builder bug

I am having a problem when I try advancing a character in character progression. When I try to go to advantages and flaws, I get the above error.

Please help.

Hello, thanks so much for your report! Could you provide a link to the character you’re encountering this issue with?

To do so, make sure to click/tap the character icon in the top left, which will open the settings panel. From there, scroll to the bottom to set the share to anyone with a link, and then copy the link there and either post it here, or send it to me in DM (if you prefer not to share it publicly)

Thank you!
