I appreciate the effort, and I also hope someone from Adobe sees this.
Before I switched to Sony's Compressed Raw files I was shooting Uncompressed then converting to DNGs, but I saw no difference in quality if I just shot directly to Compressed, so I abandoned that practice and haven't used DNGs since. I actually don't mind the sidecars though I have considered DNG to eliminate this problem.
I've had this problem in the past with DNGs and really ALL file types. I was just doing some testing to try to capture a screen recording to show exactly what's happening and I couldn't get the problem to happen—like when you take your care in to the mechanic, right?
In this testing I found a couple of things. When I coudln't get the problem to present itself, I was simplying renaming "Testing_" with a number sequence after that text, and NO New Extension line. It worked great. On DNGs, CR2s, ARWs. BUT THEN! I realized my normal file system, which is loosely based off the old Magnum negative system, has a lot of periods in it. For example, 2020.30.7R3.0001 (that works out to one line for the "2020.30.7R3." and another line for the Sequence number). So I tested again, and added a couple of extra Periods in my text string. BINGO. Not only did it fail, but it borked Bridge all together. I had to Force Quit it and reopen. I also dragged in the window so you could see the mess it leaves the file names in when it crashes. I tried it again with _ instead of . (underscores instead of periods) and it worked flawlessly. ie testing_testing_test_ [number sequence]. No problem at all. I tried again and replaced ONLY the first _ with a . to read "testing.testing_testing_" and it froze Bridge AGAIN. I guess I'm on underscores in my filenames until Adobe fixes this bug.
I have a video of this happening if it is needed (there's no way to attach the video directly to this reply).
I reported both recent crashes to Adobe via the Crash Reporter with detailed descriptions to recreate.
