I am having an issue with the twig template system - php

Question

I have opencart 3 installed on my dev box and have suddenly started getting the following error:
Fatal error: Class Twig_Loader_Filesystem contains 2 abstract methods
and must therefore be declared abstract or implement the remaining
methods (Twig_LoaderInterface::isFresh,
Twig_ExistsLoaderInterface::exists) in
/mnt/c/wsl/server/opencart/system/library/template/Twig/Loader/Filesystem.php
on line 17
I have been working on a custom template and all was going fine until I changed something in the controller of the footer. Changing it back did not resolve the issue. I have also manually cleared the cache in the OC folder and the twig folder. I also did not have the cache setting set to off so I manually made this change in the db as I get the same error trying to get into the admin.
I am at a loss. I would love any help I could get.
