Got this while running within my user directory(owned by my user) release 0.2.0, I'll try building from source and see if the issue persists. :3
uname -r : `Void Linux 6.12.11_1 #1 SMP PREEMPT_DYNAMIC Fri Jan 24 14:02:23 UTC 2025 x86_64 GNU/Linux`

Start in package:retro/main.dart at line 35 and reproduce release 0.2.0 on the reported Void Linux environment, focusing on creation of latest.log. Determine the expected behavior when the filesystem is read-only, then verify that behavior with a regression check if the project provides a suitable test location.
