Console output when running the game.

I try to run the game JustGrandmaAndMe from 1997 (Version 2.0) in Wine Staging
5.16-1.
Using a clean Wineprefix set to Winearch=win32 and Windows-Version 98 I ran the
game's "jgmd.exe" with (put into a bashscript): 
WINEARCH="win32" WINEPREFIX="/home/nutzer1/Dokumente/JGM/" WINEDEBUG=warn+all
wine "/home/nutzer1/Dokumente/LIVING_BOOKS/jgmd.exe"
(it doesn't work in a clean ~/.wine as well)

This gave me the error: err:dosmem:setup_dos_mem Cannot use first megabyte for
DOS address space, please report

Looking it up I found you can circumvent this error by doing: sudo sysctl -w
vm.mmap_min_addr=0

But now I'm getting the error:
00b8:err:ntdll:RtlpWaitForCriticalSection section 6BB42940
"../../../wine/dlls/krnl386.exe16/syslevel.c: Win16Mutex" wait timed out in
thread 00b8, blocked by 00bc, retrying (60 sec)

The retries are infinite, thus causing a softlock.

There are multiple bug reports with the same issue already. Overall it seems to
me that the issue was fixed before but somehow reappeared.

If you need the game files I will send them to you in private.
