I tried using Wine 4.12.1 with DXVK 1.3.1 instead of Steam Play 4.2-9 and it
still didn't work, crashing at the same place.

There are a few messages that are noticeable on the logs, which may indicate
the cause of this.

Using Steam Play 4.2-9:

11622.296:00ad:00d8:err:seh:call_stack_handlers invalid frame 593a5a30
(0x593c2000-0x594c0000)
11622.296:00ad:00d8:err:seh:NtRaiseException Exception frame is not in stack
limits => unable to dispatch exception.

Using Wine 4.12.1 with DXVK 1.3.1:

0162:err:seh:call_stack_handlers invalid frame 59535a50 (0x59552000-0x59650000)
0162:err:seh:NtRaiseException Exception frame is not in stack limits => unable
to dispatch exception.
0161:err:seh:setup_exception stack overflow 1552 bytes in thread 0161 eip
000000007bc8c104 esp 0000000059441000 stack

Notice these "invalid frame" values. They are the same. The DXVK versions are
different and the Wine version are different but, still, the "invalid frame" is
exactly the same.

On previous Steam Play versions, it printed similar messages with slightly
smaller values (58a3c478). I don't know what this frame which is invalid is,
but this was the only part of the (huge) logs which I could clearly see a
problem exists.

This game has some memory management problems. I commented about it and one
workaround in GitHub the issue,
https://github.com/ValveSoftware/Proton/issues/150#issuecomment-512500740,
there I explain the problem this game is having with memory management, where
it crashes once it reaches high values and requires an workaround. 3755 MB and
3868 MB are values which can easily make the game crash saying it failed to
allocate memory.

As the log messages with stack overflow show memory problems, maybe there is a
general issue which Elite Dangerous that it can't use more than 4 GB of video
memory, even if the computer has 20 GB available and DXVK says the heap value
is 14 GB.
