Bronica ETRS Advancing problem

[Fjordlapse]

My old and trusty Bronica got stuck mid roll, so after shooting a frame, when I tried to advance to the next frame it got dead stuck. I used the speed grip, but it is the same thing when I take that off and try. It will not advance.
Dark slide was out while shooting. Battery is ok. Mirror is stuck in the up position. Lens is stuck on the camera now but I got it off by removing the filmback and I went in and lowered the mirror by hand then it released the lens.
Without the filmback on and the Multi Exposure lever in horisontal position it is the same. Will not move 1 mm when advancing.
Shot a few hundred rolls on this camera without any issues but now I am a little lost and would love som help or idees to try?
I can move the mirror up and down by hand but it is like it wont stick in the down position and pops up again. The shutter botton on the body feels very loose and have no resistans or tension.
Very thankful for any help possible!

In the ETRS, the lens shutter will not open if the mirror has not swung up fully, and conversely...
...the mirror will not move down until the winding lever of the speedgrip has not moved thru one full advance stroke.(the second advance stroke moves the film to the next frame)

Thank you! Yes I know that, I was doing double strokes with the grip but than after the 3rd shot within about 30 seconds everything frooze after like a half stroke. So the problem is what you say, I just dont know how to solve it.

Apparently something has jammed within the body. I don't know what to do, if you cannot get winder to move.

Yes I guess an internal operation is needed. And I am not a good doctor. Noone had the same experience?

I've had my Etrs and Etrsi for over a decade each and no mechanical lock ups as you describe . I had an Etr before these
and I remember going into it ( forget why after all these years) and remembered it being quite complicated . The body is
probably cheaper than the repair ! Mind you , since you have nothing to loose , why not check further on line and see if
there are any videos on it's disassembly ? Good luck , Peter

Did you figure out the issue?
Are you using an electronic viewfinder?
Try removing the electronic viewfinder if you are, switch it to multiple-exposure mode, and see if you can wind/shoot.
