Control: tags -1 patchI have done more tests with vinagre. I have attached a .debdiff that fixes Vinagre's connection initialization and gives me a working RDP session.
Upstream authors of FreeRDP mentioned that Vinagre's way of using the FreeRDP API is rather old and it should be reworked by Vinagre upstream maintainers.
However, session startup now works, but maybe more flaws are ahead.See attached .debdiff for the proposed fix (and ignore the patch that was attached to my earlier post).

+Subject: [PATCH] plugins/rdp: Fix hangs with recent FreeRDP versions
+
+Connection to all my testing servers fails with "SERVER BUG: The support
+for this feature was not announced! Use /relax-order-checks to ignore"
+currently. This happens always with current FreeRDP versions after
+https://github.com/FreeRDP/FreeRDP/pull/4926 has been merged. This can be
+fixed by the usage of /relax-order-checks option, however, this option
+should be used only if necessary needed and it should not be needed in
+most of the cases. This currenlty happens always as it interfere with our
+custom OrderSupports settings. Let's use the default OrderSupports
+settings to fix this issue, which is possible thanks to
+https://github.com/FreeRDP/FreeRDP/pull/5057.
+
+See: https://gitlab.gnome.org/GNOME/gtk-frdp/-/issues/27
