Hello landing.st,
I couldn't find any message to support from your email address, also no crash reports have been signed with your email.
However, I was able to find unsigned crash report from the version 1.5.3 with the similar hardware, so it should be from your system, I believe.
I'll try to check, what caused those problems in the version 1.5.3.8469, but if it was related to the bug which has been fixed since 1.5.3 release in June 2019, we would not be able to backport the fix to 1.5 version.
The latest stable version from 1.5.x is available from the downloads page:
https://www.agisoft.com/downloads/installer/ and I hope that it works better than previous version.
So if the crashes are reproducible in your current version in a short time, you can update to 1.5.5 and check if it solves the problem.
