Help with my Mamiya M645 Super

I will start by saying this camera functions, but interestingly. The camera will take a picture, but most of the time the crank will be stuck after the shutter releases. I have exposed the internals surrounding the shutter wind and couldn't find anything out of place or in need of cleaning. The only workaround I have found so far is to put the dark-slide in, release the back, snap it back into place, then wind the crank again. Any help would be greatly appreciated!

Update on Canon P damaged viewfinder

I’m posting this for anyone who might have the same issue at some point, it is very easily repairable.

Last week I made a post here looking for advice on repairing my Canon P’s viewfinder. At first I was very nervous that the actual beam splitter had been irreparably damaged, but thankfully I learned that early serial Canon P variations have a separate, glued on piece of glass protecting the beam splitter. Later variations do not, unfortunately.

To replace the broken glass, I used picture frame glass, cut to size with a tungsten carbide glass cutter. Sanded the edges, and glued it in place with UV resin. This worked quite well and I’m beyond impressed with the results. The viewfinder is brighter/clearer than I think it’s ever been.

Thanks to everyone who gave their input, the videos on YouTube left out a lot of details on the beam splitter assembly, and some of you helped me understand it better. I also got the picture frame glass idea from someone on another post.

Need help finding information about Yashica Minister the first edition

Good morning/evening everyone!
Hi, I’m a beginner trying learning how to repair camera. I don’t really have much experience with serious repairs yet, mostly just cleaning, replacing batteries, or dealing with stuck shutters.
Recently, I found my grandfather’s old Yashica. After digging around for a few hours, I figured out that it’s a first-generation Yashica Minister. The camera isn’t in the best shape: there is some dirt on the lens barrel making it stiff/hard to rotate, and the rangefinder patch is completely faded, I can't see the orange frame line or the focusing patch at all.
I’m planning to take off the top plate to inspect the rangefinder mirrors. However, I haven't been able to find any guides or teardown videos showing a model with this exact top plate design. My main issue right now is that I can't figure out how to remove the ASA/LVS dial/knob, which seems to be connected to the light meter assembly.
If anyone has experience disassembling this specific camera or knows how to remove that part safely, I would really appreciate your guidance. Any help, tips, or pointers would be warmly welcomed!
Thank you so much in advance!
