Apple Imac interittantly crashing

Hi, hope someone might be able to help / assist with this one.
I recently upgraded an Imac to macOS Sequoia version15.6.1.
Since upgrading my mac crashes intermittantly. Despite going through closing everything and ensuring all apps are updated etc I just cant seem to put my finger on what is causing the issue.
I took my mac to the Apple Store and they diagnosed that there was an error on the logic board and suggested that be replaced. I was happy to replace as the issue makes it quite worrying when working on larger files on this mac. I had the Logic Board and therefore also a new hard drive installed and got the mac back last week. Today the issue has happened again. I know I could go back to Apple and start again but I wondered if anyone has experienced the same thing and knows of a fix or workaround. I expect this is software driven as Apple have run all diagnostics now and say the machine is good also it didn't do this prior to upgrading the OS.

Appologies for the war and peace message.

The error I get when it restarts is:

Looks like a Adobe software component is crashing
Exception Type: EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Termination Reason: Namespace SIGNAL, Code 6 Abort trap: 6
Terminating Process: com.adobe.Acrobat.RemoverTool [229]
When iMac crash, is this the same process every time?
 
Your mac is being crashed by the Adobe Acrobat removal tool.
I imagine it's a compatibility issue after you upgraded the OS
The Remover Tool scans for installed components and registry/plist entries. If some files are missing, locked, or have unexpected permissions, the tool may crash when it encounters them. That could explain why it sometimes runs fine and sometimes aborts.
I think there must be something left over from when you installed Acrobat that is causing it to be launched. I don't know why
What might have happened is you uninstalled Acrobat yourself- dragged it to the bin perhaps- and didn't use the tool. Or maybe you used it but it didn't do the job properly and can't finish.
I'm not really sure but what you posted said it's that so maybe try downloading a new version of Acrobat and uninstalling it with the uninstaller that comes with it and see if that cures it. Or maybe even dragging the uninstaller to the bin- but I don't know but that's where you've got to go

Crash reports indicate your iMac is Intel model but you never specify which model and year. I would consider replacing the memory (assuming your iMac model has user installable RAM) and testing. You can buy 16GB (2x 8GB) modules pretty cheap new or even cheaper on eBay.
 
You've had a few replies but none from anyone that "has experienced the same thing" as you asked.

Since the logic board problem was diagnosed at the Apple Store I'd be inclined to go back there for a check-up.

Good advice from Brian. Had sorta similar problems with same age & older iMacs at work. Memory seemingly fixed one, then it came back later & near everything was switched (MLB+) & it still panicked. Apple replaced it.
