“has a comma at the end”
应该是latexshop某次更新之后出现该问题：
https://tex.stackexchange.com/questions/156377/when-running-bibtex-with-a-statement-that-has-a-comma-at-the-end-this-is-obscur

解决方案也很匪夷所思，只要在作者一栏额外添加一个大括号就行:

@article{belytschko_1984_hourglass,author = {Belytschko, Ted and Ong, Jame Shau-Jen and Wing Kam Liu,  and Kennedy, James M.},month = {05},pages = {251-276},title = {Hourglass control in linear and nonlinear problems},doi = {10.1016/0045-7825(84)90067-7},urldate = {2022-02-06},volume = {43},year = {1984},journal = {Computer Methods in Applied Mechanics and Engineering}
}

to
