i use ThrottleStop for 2 years and didn't have a problem like this.
ThrottleStop has not changed so something on your computer must have recently changed. Have you updated the BIOS recently? Perhaps a Windows Update forced this upon your computer. ThrottleStop shows that the CPU is using microcode version 0xCC. Do you have any previous FIVR screenshots from a month or so ago that show a different microcode version?
In the TPL window, change the PP0 Power Limit from 50 back to 0 and press Apply. Clear the PP0 Power Limit check box and press OK to save this setting. Most recent computers do not need to use the PP0 setting. I do not think this is related to your problem but it is the only thing I see that is not quite right.
I have heard that recent Nvidia GPU drivers might be playing around with the CPU power limits. If you have recently updated the Nvidia GPU driver, try going back a few versions.
The log file you posted shows that an embedded controller (EC) is setting the power and current limits to low values. ThrottleStop has no control over the EC limits that a manufacturer sets. I do not know why this would have recently changed. Can your battery still hold a charge for a reasonable amount of time? Are you using the original Acer OEM power adapter and an Acer OEM battery? Either one of those might be causing the issue you are having.
Instead of checking MMIO Lock, clear that box, reboot and try checking the Sync MMIO box instead. Some software (Nvidia driver) might be checking if the MMIO Lock bit is set and could be doing something different to the power limits based on this.
My best guess is that an Acer BIOS update is the root cause of your problem.
