Hello Iroidhdr17, I am sorry to hear your references broke.
Sometimes, this can happen due to filepath changes, especially with downloaded files. I would also check if the project itself required any plugins, in case a reference may be related to that. Regardless, I did find a relatable thread that does go over a similar circumstance to your current conundrum.
Here, the members speak on using reference viewer and version control for people who want to host their projects for download.
The plugin suggestion from herb64 looks pretty neat, but just as well, I cannot speak on the validity of this being a solution. I like herb64’s idea of right clicking the broken variable and just creating it from there. After that, I would check where the variable is initially set to ensure everything is as expected.
Have a great day.
