Estimating Camera locations never ends

[Damian]

Hello

I am aligning 4000 cameras in one chunk and an issue happens: everytime when the alignment reaches "Estimating Camera locations" the process bar stops at some stage, the "time left" slowly goes down to 0 and then dissaperas. After that nothing happens [printscreen in attachement].  When I clikc "pause" or "cancel" buttons grey out and stay like that for ever.
Before that, I aligned 4500 cameras in same project in another chunk with no problem.

Alignment options are 40 000/ 4 000, earlier I tried with 30 000/3 000 - same result.

I attach a log
Thank you for quick answer.

Hello Damian,

Is it possible to perform only image matching operation for the project (using a Python call), save the project in PSZ format and send it to us so that we could try to reproduce the issue?

Also were you observing the considerable CPU activity during the alignment process? Additionally please specify, if any uncommon options have been used in the Camera Calibration dialog, such as fixed parameters, photo-invariant parameters, rolling shutter compensation.
