Combining Files Crashes Acrobat

[Angelic_Hanz1557]

Hey all! On a large selection of files that I try to combine acrobat freezes and crashes. There are some files that do work. But on a large portion the app or the web app both crash when trying to combine them. I have an older windows 11 24h2 dell laptop. Ive reinstalled, repaired, adobe cleaned  several times. Everything is up to date. But I cant figure out why it keeps happening to this random set of files.

@Angelic_Hanz1557 the only thing I can think of is one of th PDFs is corrupted. Try smaller batches. Once a small batch is combined, 'save'. Then combine another small batch and save again. Keep on doing this until it crashes. 

Reopen the last saved combined file, and make the next batch even smaller. To the point, where you will find the 'culprit!'
