Segfaults: Can't modify entry left running overnight/can't continue using ID

I recently brew installed timewarrior on macOS sonoma.
```
timew 1.7.1
Platform: Darwin

Compiler:
Version: Apple LLVM 15.0.0 (clang-1500.1.0.2.5)
Caps: +stdc +stdc_hosted +LP64 +c8 +i32 +l64 +vp64 +time_t64
Compliance: C++17

Build Features
Built: Jan 16 2024 12:35:02
CMake: 3.28.1
Build type: Release
```

Redacted output of the situation looks like this:

```
$ timew summary :week

Wk Date Day Tags Start End Time Total

@1 ticket 9:15:00 - 1:22:19 10:37:19
```

timew help modify suggests I can fix it with the following command, but I get

```
$ timew modify end @2 2024-05-16T17:00:00
[1] 90947 segmentation fault timew modify end @2 2024-05-16T17:00:00
```

Also tried
```
$ timew shorten @2 30min
[1] 90963 segmentation fault timew shorten @2 30min
```

Also was recommended to edit a *.data file directly; however, I am just now finding that I can't locate where those files are stored.

Little help???

Reproduce the crash on macOS with the reported `timew modify end @2 2024-05-16T17:00:00` and `timew shorten @2 30min` commands using the supplied overnight entries. Start by tracing the failing command path and determine where the relevant `.data` files are stored. Done means both commands handle the entry without a segmentation fault.
