I have been seeing too many kernel crashes in 13.1. In one script, which runs for almost 10 hrs, it used to run from start to beginning in 13.01 without one single kernel crash. Now in 13.1, so far I had to restart it 7 times (as kernel goes away). Only change is the version number and also adding IncludeSingularSolutions -> True to DSolve. May be the cause is IncludeSingularSolutions. I do not know. Since there is no error message or anything to say why it crashed.

@kirkus Thanks for trying it out!

@Nasser Would you be able to test this problem I mentioned in the above-linked question on Windows?

Also, if someone can try it on an Intel Mac or Linux, that would be great.

@Szabolcs I also have no issues on Windows 10 with 13.1.0

@Szabolcs I will install the package and try them as you described in the post and will let you know. hopefully later tonight. Waiting for something to finish on my Mathematica 13.1. I am on windows 10 pro, with 128 GB RAM. my PC is intel i9-12900k
