Unable to update/sync exp into existing project (Pavlovia)

OS (e.g. Win10): Win10
PsychoPy version (e.g. 1.84.x): 2020.1.3.
What are you trying to achieve?: I want to sync some changes I made in builder with the project’s repository in gitlab. My existing HTML doesn’t update, and neither does the JS file, so Pavlovia keeps running the old version of the experiment. I added some files which were successfully pushed as resources, but very basic changes such as changing the contents of a text component are not updated. I’ve been having various issues with synchronization ever since I started working with 2020.1.3. (which I have to by necessity).

What specifically went wrong when you tried that?:

Here’s the error message I get when I try compiling:

wx._core.wxAssertionError: C++ assertion “Assert failure” failed at …..\src\aui\framemanager.cpp(1521) in wxAuiManager::LoadPaneInfo(): Bad Perspective String

What did you try to make it work?: I tried deleting the existing project and its respectful git folder and creating a new project - that didn’t solve the issue. I also tried disabling different components to see whether JS compiles. Also didn’t work.
