seemingly changing the name of the Vehicle article in any way causes a bug that then makes the article unusable

Steps to Reproduce

im not entirely sure how to explain this, at first i thought it seems that specifically the word "spider" or "spiders" isnt liked in the Vehicle article template name, because everytime i write it, a warning pops up saying the autosave isnt functional either because my internet is disconnected or using unsupported characters, but i tested it on a computer in a totally different building connected to a totally different and much better connection (and my own phone on both networks) and still had the error pop up. with some deeper tinkering, it seems the act of adding too/deleting/altering the name of spefically the Vehicle article template now causes a bug that makes the entire article unusable and everytime the user stops typing it causes the warning to flash, using the "attempt to fix" button does not work and closing the box with the X or "got it" just makes it pop up again near instantly. i am unsure how far/if others are experiencing the same issue as i have not heard anything though, testing Character, Geogrophy, Building and Meterials do not seem to produce the same issue and they save fine no matter how many or quick changes are made
