several things.
The only plugins involved are yanfly's plugins for the savecore and the newgameplus, that simplyfies things.
Please check if you have all required other yanfly plugins installed, and if yanfys plugins are in the correct order as shown on his website - those are the two most common errors with his plugins.
Additionally, please post links to those two plugin websites here, so that we can check them ourselves, and post a screenshot of your plugin manager if you don't know how to check order and required plugins.
However, the rest of the messages point to thing that might cause you other problems later, so I adress them as well.
Is this the version of the project you work on directly? If yes, please move it out of the cloud(the onedrive part of the filepath).
You can use a cloudservice only for backups or moving the project - the RM editors work differently on their files than most other programs, and working with them sirectly on a cloud-enabled folder will place your project at risk of being damaged. If you try to edit a project that is saved on the cloud, sooner or later the cloud function will clash with RMMV's save function, destroying files - that is only a question of when, not if.
and you should also edit whatever plugin you're using for font changes to use a font you provided, to get rid of the file not found messages...
