Hi @ajulioo,
Looks this is a similar issuse as posted here : Change to Token when Commit existing Project to GitHub - Help / Studio - UiPath Community Forum
I dont have an answer for you, but I do empathize with you. This transition from Credentials to Token is a change which UiPath should have been aware of. So hopefully you will see some official responses from UiPath in this or other thread.
Although if UiPath has to updated it, it will mean that you have to either upgrade or reinstall UiPath Studio.
@loginerror Looks like many may face this issue in the coming days.
