Shotcut is not closing process

[QDSOV]

I reported something related in the linked thread concerning 18.05.08 which still occurs with 18.06.02:

PC in overdrive, SC unresponsive

I’m assuming this is a bug because it’s only started happening with 18.05.08 and it is intermittent, but can happen several times a day Until I found out what it was it was quite frustrating but it’s easy to fix when it happens. First time was on the day I installed 18.05.08. I have done a reinstall with the registry settings overwritten for a separate reason but it still occurs. Every now and again whilst running SC the program will become extremely slow and unresponsive and audio playback is …

I’ve also never used html effects in anything I’ve done.

Since I made the thread I have noticed one thing about when it occurs. It often happens randomly, but the one set of circumstances which almost always causes it is when I have mistakenly had two instances of SC open at once. When I close the unwanted one down, the desired instance is crippled - no sound on timeline playback, and very slow, stuttering video playback. Once I shutdown the shotcut process in task manager, which is often consuming 90%+ of my CPU resources, everything runs normally again.
