Hello, I have encountered some problems when using EvoSuite, and I would like your guidance to solve them. Looking forward to your reply. Thank you!

Evosuite is normal on some simple projects, but there will be the following errors on our company's projects. At first, I suspected the problem of my JDK. But I found the same problem with my colleague's computer.
