New S10+ GBWhatsapp issue - can't use whatsapp web or start a new mess

Hi, I'm hoping someone can assist me here, I failed miserably at transferring over my previous chats from my s9 to my s10+ via for GBWhatsApp . I admittedly was messing with the folder structure on the phone and made some obvious mistakes. GBwhatsapp will load now however I can't initiate a new message (it just brings me right back to the initial screen) what's app web won't work either. How do I completely start from scratch and resolve any issues with corrupted folders or cache?
