papers3 在导入 pdf 时发生闪退, 分析原因是软件无法写入导致的.
由于本人不懂代码, 勉强查到了一些可能的原因:

由于 apple silicon 的 Write Protections 导致

附上崩溃报告, 还请专业人士指点如何才能让这个软件具有写入磁盘的能力, 谢谢!
(SIP 关闭与否都会崩溃)

感觉是别的原因导致的
0x0 肯定不会是指令的内存啊

@dingwen07 #3 感觉很奇怪, 就是找不到原因, 感觉找到原因后这软件可能还有救

你发的这两个链接是关于 JIT 编译器需要注意的 Apple Silicon 内存写保护特性，感觉和你这个软件以及这个错误没什么关系。错误报告里看起来是在试图访问空指针

@elementp #5 这文献管理软件功能啥都好使, 就是导入 pdf 会闪退, 请问这种问题可以通过对应用进行修改解决吗?
