Logic Pro X - Constant crash of older projects

Dear all,

I recently deleted some files which were irrelevant for Logic or my production. Or at least that's what I thought. Because after that, I can't open certain projects anymore without Logic crashing.

It will load up the Plug-Ins and samples, show the project for a split second an crash instantly. Only the program is crashing and I can restart it if I like.

So far I tried resetting the preferences and deactivating the Plug-Ins.

I'm desperate for help so if anybody could help me with the crash report, that would be really great. There must be some kind of file or Plug-In which is in these certain projects causing the trouble. Because other, smaller projects will open.

Thank you so very much for your help.
