I can confirm that the latest version of CCleaner still shuts down when automatic browser cleaning is enabled, I am happy for support to contact me by email.

I will make sure I am up to date when I get home from work and turn automatic browser cleaning back on, I will report back after testing.

I checked the log and I found some failed to open file errors and a number of crashes all the same... 1685909867223647290 4 APPCRASH Not available 0 CCleaner64.exe 5.68.0.7820 5ee8e43b ntdll.dll 10.0.18362.815 b29ecf52 c0000005 00000000000072a6 \\?\C:\ProgramData\Microsoft\Windows\WER\Temp\WERAB2F.tmp.WERInternalMetadata.xml \\?\C:\ProgramData\Microsoft\Windows\WER\ReportArchive\AppCrash_CCleaner64.exe_495b734d88af1b15e2e28763ec3e8ad6101315_dee105cb_0c562393-2339-415f-aeaa-c9ade9714190 0 3aa98881-9472-405e-afd9-47029aa013b5 268435456 9a2589bf8ace2cb067658e178731043a 0

I disabled auto browse cleaning and that seems so far to have been successful.

Ok it appears that Steam and Discord are not the only thing causing the issue, CCleaner stopped running after I shut Fire Fox down as well, I checked the Task Manager and it had indeed closed the program.

Thanks for looking into this it's much appreciated, I'm sure I checked task manager in the past but to be honest I can't remember if CCleaner was running or not, I've not had an issue since I whitelisted Steam and Discord as yet but time will tell, I will update this post if whitelisting continues to work as it may give some clue as to what is causing the issue in my case.

Yes I have smart cleaning enabled but not the option to close the program after custom clean, as you say it happening only occasionally is like the rattle in your car that always disappears when you take it to be fixed. For now, I have excluded both Steam and Discord, as the two apps I close regularly from the system tray this may be a good test to check if they are indeed causing the shut down.

I am using CCleaner Pro 5.70.7909 with Windows 10 Pro, Version 1903, OS Build 18362.1082. I have noticed when I shut down programs such as Steam and Discord from the system tray hidden icons (But not only these programs) that the CCleaner icon disappears and shuts down, this was also happening occasionally in the previous version but seems more frequent in the latest version.
