Hi Revonda,
Thanks for posting back and sorry for my late reply.
I go through your post carefully. Regarding the first error message, one member mentioned that this can be caused by the Check In/Out function. So, I suggest you check the "Require Check Out" setting in the Library settings. Go to the library in SharePoint, Settings, More Library settings, and Versioning Settings. Ensure that "Require Check Out" is set to No. If not, please change it to No, then check again.
Regarding the second error message, I suggest you check the following points.
- Please ensure that the Version column is not configured as an Indexed Column.
Go to the library in SharePoint, Settings, More library settings, under the Columns section, and click "Indexed columns". Ensure that the Version column is not in the list. If it is in the list, please click it and then delete it.
- Based on this article, the error message can be caused by a problematic column being included in the content type. Please go to Library settings and check if you can see a "Content Types" section and see multiple content types. If you can see multiple content types, please set another content type as default and make other content types invisible by clicking "Change new button order and default content type". After that, please check if the issue still occurs.

If the above suggestions don't help, to troubleshoot the problem further, I suggest you contact your admin or IT department to raise a support ticket via Microsoft 365 Admin Center> Support> New service request. That support team there will have the correct channel and resources to help you investigate more and find what exactly reason has caused this problem.
Sorry for the inconvenience that happened to you. Appreciate your understanding and patience.
