First time testing, multiple bugs + crash

[theRolento]

Describe the bug

1. Save PDF just crash the program.
2. No errorlog is generated.
3. No debuglog is generated (option checked)

To Reproduce
Steps to reproduce the behavior:

1. Import PDF (410 pages)
2. Enable OCR settings (tried every combination with languages and mode)
3. Save PDF
4. Stuck on 0 for some time and it just crash
5. Check Data folder (portable) no errorlog and no debuglog

Expected behavior
It should generate and save the PDF and it should at least generate the debuglog.

Desktop (please complete the following information):
OS: Windows 11
Version: 8.0b3 Portable

Same thing happens with 7.5.3.
Basically i can't use naps2

[cyanfish]

Can you try this test version and see if it makes any difference?

Nope, just tried. Not working it crashes like before.
If i manually select a bunch of pages apparently works, like 60-70 pages at once. Starting from 80 it's random, it can crash or it can work. Starting at around 100+ pages it always crashes.
