error message

After upgrading wine to 10.3-1 I can not start Meta Trader 4. 
There is an error message: "A debugger has been found running in your system.
Please, unload it from memory and restart your program", as shown in the
attachment.

Downgrading wine to its previous version: wine 10.2-2 temporary has solved the
issue.

Please attach the terminal output.

Additionally, since this is a regression, it would super helpful if you could
run a regression test:

Does this program have a free demo/download?

MetaTrader 4 is available as a free demo/download with several brokers, for
example here: https://download.mql5.com/cdn/web/11419/mt4/tickmilleu4setup.exe
or here: https://download.mql5.com/cdn/web/ig.group.limited/mt4/ig4setup.exe

The regression test seems too complicated for me and unfortunately I won't be
able to do it.

Usually, I start Meta Trader 4 by clicking on the icon and then I don't see any
messages, as in the terminal.

A try to start MT4 in the linux terminal under wine 10.3-1  generates errors as
below and MT4 does not start.

(I can't run here Meta Trader 5 too - as signaled by other users in other
threads.)

MT4 starting in the linux terminal under wine 10.2-2 generates messages as
below and  runs successfully.

(Meta Trader 5 also runs here without any problems.)

The message "debugger has been found" happens when running in a 64-bit wine
prefix.

The Metatrader 4 installer usually is 64-bit, while the application itself
(terminal.exe) is 32-bit. When installing in a 64-bit prefix to fulfill the
installer and then transferring the installed application to a 32-bit prefix,
Metatrader 4 crashes at startup.

A git bissect shows the offending commit as:

https://gitlab.winehq.org/wine/wine/-/commit/dc718fd33b23a6104a0fa2e971a3586...

This commit is responsible for both issues I described in my previous comment:

- the original OP issue: the message "debugger has been found" shows at startup
in a 64-bit wine prefix, preventing Metatrader 4 to run.
- crash at startup in a 32-bit wine prefix

After upgrading Wine to 10.4 the issue still exists, both with MT4 and MT5.

A question: We know which commit in Wine is responsible for this issue. So when
Wine will be fixed?
