Your first steps in getting help would be logs, and mediainfo since we have no idea if the file you are having problems with has anything to do with this thread.
To get a better understanding of the problem you are experiencing we need more information from you. The best way to get this information is for you to upload logs that demonstrate your problem. You can learn more about how to submit a useful support request here.
So, in summary:
activate the logging
reboot the OSMC device
reproduce the issue
upload the log set either using the Log Uploader method within the My OSMC menu in the GUI or the ssh method invoking command grab-logs -A
publish the provided URL from the log set upload, here
Thanks for your understanding. We hope that we can help you get up and running again shortly.
Kodi v18 alpha is still in quite early stages (although the first beta is due in a couple of days).
There are some fixes for resetting the HEVC decoder that can be added soon.
I don’t have a solution for v18 at this time as it’s still experimental. This thread is from a year ago. I think the issues are largely fixed with v17 but would need a sample to test

I’d suspect a bad encode here.
The freeze/skip frame is about this one (stopping the video at the exact point on my PC is difficult):
