Import/Export Panel Error

[Darius1968]

I'm gonna attach my backup log file here, reflecting a necessary force-close of IMatch (latest version - 2020.5.6) because it encountered an error (the dialog displayed "IMatch has encountered a problem and needs to close.") from which the program was frozen in its tracks.  This, after simply dragging-and-dropping a TIF file onto the Import/Export Panel for the purpose of a file conversion.

Nothing unusual in the log. Some ExifTool warnings, e.g. about trying to extract metadata from a vue scan log file, which is inaccessible (probably locked).
Not sure if you should really manage temporary log files in your DAM.

Did IMatch produce a dump file? https://www.photools.com/help/imatch/#im_dumpfile.htm
If not, the error was caused by something external (driver, codec, virus checker) and Windows just closed IMatch in response.

I had used a scanning software (VueScan) to scan an image, however, that program was long-since closed, as well as the scanner being powered-off and its USB disconnected from the PC when I attempted the file conversion via Import/Export. 
I don't intentionally use IMatch to manage log files.  Like I said, all that happened was for IMatch to freeze in its tracks, not letting me click the dialog's OK button to get untracked.  I didn't think that a dump file was created.  I just issued a force-close when trying to OK the dialog was unresponsive, but as I read the documentation you provide about dump files, it may be my fault partially in that I did not wait long enough for the dump file to be created, as I should have given several minutes, which I can't say that I did.

IMatch reports

Failed to calculate CRC for file C:\Users\Darius\Pictures\VueScan\vuescan.log

which just means that this folder is indexed in your database and IMatch could (at this time) not access the log file.
It later did. Log files are a standard format supported by IMatch (as a generic text) file, so it tried to process it.
Later it worked, probably the lock was gone.

Without a DUMP file or repro steps, there is little I can do.

Just a quick note: VueScan by default creates a ..\Pictures\Vuescan folder where it keeps the vuescan log file. But I've never had an issue with the log file in IMatch. Vuescan is pretty widely used, so I'm sure by many other IMatch users.
